World Heritage List

The ruins of São Miguel das Missões in Brazil, and those of San Ignacio Miní, Santa Ana, Nuestra Señora de Loreto and Santa María la Mayor in Argentina, lie at the heart of a tropical forest. They are the impressive remains of five Jesuit missions, built in the land of the Guaranis during the 17th and 18th centuries. Each is characterized by a specific layout and a different state of conservation.

This site is an extensive Inca communication, trade and defence network of roads covering 30,000 km. Constructed by the Incas over several centuries and partly based on pre-Inca infrastructure, this extraordinary network through one of the world’s most extreme geographical terrains linked the snow-capped peaks of the Andes – at an altitude of more than 6,000 m – to the coast, running through hot rainforests, fertile valleys and absolute deserts. It reached its maximum expansion in the 15th century, when it spread across the length and breadth of the Andes. The Qhapac Ñan, Andean Road System includes 273 component sites spread over more than 6,000 km that were selected to highlight the social, political, architectural and engineering achievements of the network, along with its associated infrastructure for trade, accommodation and storage, as well as sites of religious significance.

Chosen from the work of Le Corbusier, the 17 sites comprising this transnational serial property are spread over seven countries and are a testimonial to the invention of a new architectural language that made a break with the past. They were built over a period of a half-century, in the course of what Le Corbusier described as “patient research”. The Complexe du Capitole in Chandigarh (India), the National Museum of Western Art, Tokyo (Japan), the House of Dr Curutchet in La Plata (Argentina) and the Unité d’habitation in Marseille (France) reflect the solutions that the Modern Movement sought to apply during the 20th century to the challenges of inventing new architectural techniques to respond to the needs of society. These masterpieces of creative genius also attest to the internationalization of architectural practice across the planet.

The Fertö/Neusiedler Lake area has been the meeting place of different cultures for eight millennia. This is graphically demonstrated by its varied landscape, the result of an evolutionary symbiosis between human activity and the physical environment. The remarkable rural architecture of the villages surrounding the lake and several 18th- and 19th-century palaces adds to the area’s considerable cultural interest.

This serial property of 111 small individual sites encompasses the remains of prehistoric pile-dwelling (or stilt house) settlements in and around the Alps built from around 5000 to 500 B.C. on the edges of lakes, rivers or wetlands. Excavations, only conducted in some of the sites, have yielded evidence that provides insight into life in prehistoric times during the Neolithic and Bronze Age in Alpine Europe and the way communities interacted with their environment. Fifty-six of the sites are located in Switzerland. The settlements are a unique group of exceptionally well-preserved and culturally rich archaeological sites, which constitute one of the most important sources for the study of early agrarian societies in the region.

It covers almost 600km of the whole Roman Empire’s Danube frontier. The property formed part of the much large frontier of the Roman Empire that encircled the Mediterranean Sea. The Danube Limes (Western Segment) reflects the specificities of this part of the Roman Frontier through the selection of sites that represent key elements from roads, legionary fortresses and their associated settlements to small forts and temporary camps, and the way these structures relate to local topography. 

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom). All of these towns developed around natural mineral water springs. They bear witness to the international European spa culture that developed from the early 18th century to the 1930s, leading to the emergence of grand international resorts that impacted urban typology around ensembles of spa buildings such as baths, kurhaus and kursaal (buildings and rooms dedicated to therapy), pump rooms, drinking halls, colonnades and galleries designed to harness the natural mineral water resources and to allow their practical use for bathing and drinking. Related facilities include gardens, assembly rooms, casinos, theatres, hotels and villas, as well as spa-specific support infrastructure. These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.

The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause. The original arc consisted of 258 main triangles with 265 main station points. The listed site includes 34 of the original station points, with different markings, i.e. a drilled hole in rock, iron cross, cairns, or built obelisks.

Twenty-three belfries in the north of France and the belfry of Gembloux in Belgium were inscribed in 2005, as an extension to the 32 Belgian belfries inscribed in 1999 as Belfries of Flanders and Wallonia. Built between the 11th and 17th centuries, they showcase the Roman, Gothic, Renaissance and Baroque styles of architecture. They are highly significant tokens of the winning of civil liberties. While Italian, German and English towns mainly opted to build town halls, in part of north-western Europe, greater emphasis was placed on building belfries. Compared with the keep (symbol of the seigneurs) and the bell-tower (symbol of the Church), the belfry, the third tower in the urban landscape, symbolizes the power of the aldermen. Over the centuries, they came to represent the influence and wealth of the towns.

The transnational serial property is an Enlightenment experiment in social reform. These cultural landscapes demonstrate an innovative, highly influential 19th-century model of pauper relief and of settler colonialism, which today is known as an agricultural domestic colony. The property encompasses four Colonies of Benevolence in three component parts: Frederiksoord-Wilhelminaoord and Veenhuizen in the Netherlands, and Wortel in Belgium. Together they bear witness to a 19th century experiment in social reform, an effort to alleviate urban poverty by establishing agricultural colonies in remote locations. Established in 1818, Frederiksoord (the Netherlands) is the earliest of these Colonies and home to the original headquarters of the Society of Benevolence, an association which aimed to reduce poverty at the national level. The other component parts were constructed between 1820 and 1823. In Frederiksoord-Wilhelminaoord, small farms along planted avenues were built for families and this Colony was referred to as ‘free’. Wortel is a hybrid Colony, first built for families and called ‘free’, later inhabited by beggars and vagrants and catalogued as ‘unfree’. In Veenhuizen large dormitory structures and larger centralized farms along planted avenues were built for orphans, beggars and vagrants that worked under the supervision of guards. This colony was called ‘unfree’. Each component part has a distinctive spatial character, connected to the target group for which it was built, and a specific organization of the work, with either family farms or institutions with working farms for groups of individuals. The Colonies were designed as panoptic settlements along orthogonal lines. They feature residential buildings, farm houses, churches and other communal facilities. At their peak in the mid-19th century, over 11,000 people lived in such Colonies in the Netherlands. In Belgium their number peaked at 6,000 in 1910.

All along the Western Front of the First World War, which stretched for some 700 km from the North Sea to the Franco-Swiss border, a series of 139 funerary and memorial sites bear witness to the common desire of the various parties involved in the conflict to honour their children who fell in battle. This objective takes the form of individual graves and/or memorials listing the names of the missing. Places dedicated to meditation, remembrance and tributes are specially created. Beyond the diversity in size, location and design, there is a clear desire to create spaces that are worthy of the sacrifice made. This is reflected in the choice of noble materials, as well as in calls for renowned architects, botanists, landscape architects and artists to design sites of exceptional architectural, artistic and landscape quality. These sites are visited daily by pilgrims, individual visitors, official delegations, school groups, local community representatives and descendants. They bear witness to funerary and memorial practices that are still relevant today, as remains discovered by chance or during archaeological excavations are still buried there with all honours. These commemorative sites represent a heritage that almost literally belongs to the whole world, spreading a message of reconciliation that is still very topical.

The Koutammakou landscape in north-eastern Togo and neighbouring Benin is home to the Batammariba, whose remarkable mud tower-houses are known as takienta (sikien in the plural). Nature is strongly associated with the rituals and beliefs of society here. The landscape is exceptional due to the architecture of the tower-houses which reflect the social structure; its farmland and forest; and the associations between people and landscape. The buildings are grouped in villages, which also include ceremonial spaces, springs, sacred rocks and sites reserved for initiation ceremonies.

This site is an extensive Inca communication, trade and defence network of roads covering 30,000 km. Constructed by the Incas over several centuries and partly based on pre-Inca infrastructure, this extraordinary network through one of the world’s most extreme geographical terrains linked the snow-capped peaks of the Andes – at an altitude of more than 6,000 m – to the coast, running through hot rainforests, fertile valleys and absolute deserts. It reached its maximum expansion in the 15th century, when it spread across the length and breadth of the Andes. The Qhapac Ñan, Andean Road System includes 273 component sites spread over more than 6,000 km that were selected to highlight the social, political, architectural and engineering achievements of the network, along with its associated infrastructure for trade, accommodation and storage, as well as sites of religious significance.

This serial property combines 28 sites, located in Bosnia and Herzegovina, western Serbia, western Montenegro and central and southern Croatia, representing these cemeteries and regionally distinctive medieval tombstones, or stećci. The cemeteries, which date from the 12th to 16th centuries CE, are laid out in rows, as was the common custom in Europe from the Middle Ages. The stećci are mostly carved from limestone. They feature a wide range of decorative motifs and inscriptions that represent iconographic continuities within medieval Europe as well as locally distinctive traditions.

The ruins of São Miguel das Missões in Brazil, and those of San Ignacio Miní, Santa Ana, Nuestra Señora de Loreto and Santa María la Mayor in Argentina, lie at the heart of a tropical forest. They are the impressive remains of five Jesuit missions, built in the land of the Guaranis during the 17th and 18th centuries.

This property is a 5,000 km section of the extensive Silk Roads network, stretching from Chang’an/Luoyang, the central capital of China in the Han and Tang dynasties, to the Zhetysu region of Central Asia. It took shape between the 2nd century BC and 1st century AD and remained in use until the 16th century, linking multiple civilizations and facilitating far-reaching exchanges of activities in trade, religious beliefs, scientific knowledge, technological innovation, cultural practices and the arts. The thirty-three components included in the routes network include capital cities and palace complexes of various empires and Khan kingdoms, trading settlements, Buddhist cave temples, ancient paths, posthouses, passes, beacon towers, sections of The Great Wall, fortifications, tombs and religious buildings.

This property consists of 6 components of defence works in Italy, Croatia and Montenegro, spanning more than 1,000 km between the Lombard region of Italy and the eastern Adriatic Coast. The fortifications throughout the Stato da Terra protected the Republic of Venice from other European powers to the northwest and those of the Stato da Mar protected the sea routes and ports in the Adriatic Sea to the Levant. They were necessary to support the expansion and authority of the Serenissima. The introduction of gunpowder led to significant shifts in military techniques and architecture that are reflected in the design of so-called alla moderna / bastioned, fortifications, which were to spread throughout Europe.

Erzgebirge/Krušnohoří (Ore Mountains) spans a region in south-eastern Germany (Saxony) and north-western Czechia, which contains a wealth of several metals exploited through mining from the Middle Ages onwards. The region became the most important source of silver ore in Europe from 1460 to 1560. Mining was the trigger for technological and scientific innovations transferred worldwide. Tin was historically the second metal to be extracted and processed at the site. At the end of the 19th century, the region became a major global producer of uranium. The cultural landscape of the Ore Mountains has been deeply shaped by 800 years of almost continuous mining, from the 12th to the 20th century, with mining, pioneering water management systems, innovative mineral processing and smelting sites, and mining cities.

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom).

These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.

The Moravian Church Settlements is a transnational serial extension of Christiansfeld, a Moravian Church Settlement (Denmark), already inscribed on the World Heritage List. The extension includes three municipalities founded in the 18th century: Herrnhut (Germany), Bethlehem (United States of America), and Gracehill (United Kingdom of Great Britain and Northern Ireland). Each settlement has its own architectural character based on ideals of the Moravian Church but adapted to local conditions. Together, they represent the transnational scope and consistency of the international Moravian community as a global network. There is an active congregation present in each component part, where traditions are continued and constitute a living Moravian heritage.

The site consists of four large groups of stone circles that represent an extraordinary concentration of over 1,000 monuments in a band 100 km wide along some 350 km of the River Gambia. The four groups, Sine Ngayène, Wanar, Wassu and Kerbatch, cover 93 stone circles and numerous tumuli, burial mounds, some of which have been excavated to reveal material that suggest dates between 3rd century BC and 16th century AD. Together the stone circles of laterite pillars and their associated burial mounds present a vast sacred landscape created over more than 1,500 years. It reflects a prosperous, highly organized and lasting society.

The ‘Roman Limes’ represents the border line of the Roman Empire at its greatest extent in the 2nd century AD. It stretched over 5,000 km from the Atlantic coast of northern Britain, through Europe to the Black Sea, and from there to the Red Sea and across North Africa to the Atlantic coast. The remains of the Limes today consist of vestiges of built walls, ditches, forts, fortresses, watchtowers and civilian settlements. Certain elements of the line have been excavated, some reconstructed and a few destroyed. The two sections of the Limes in Germany cover a length of 550 km from the north-west of the country to the Danube in the south-east. The 118-km-long Hadrian’s Wall (UK) was built on the orders of the Emperor Hadrian c. AD 122 at the northernmost limits of the Roman province of Britannia. It is a striking example of the organization of a military zone and illustrates the defensive techniques and geopolitical strategies of ancient Rome. The Antonine Wall, a 60-km long fortification in Scotland was started by Emperor Antonius Pius in 142 AD as a defense against the “barbarians” of the north. It constitutes the northwestern-most portion of the Roman Limes.

A landscaped park of 559.9 ha astride the Neisse River and the border between Poland and Germany, it was created by Prince Hermann von Puckler-Muskau from 1815 to 1844. Blending seamlessly with the surrounding farmed landscape, the park pioneered new approaches to landscape design and influenced the development of landscape architecture in Europe and America. Designed as a ‘painting with plants’, it did not seek to evoke classical landscapes, paradise, or some lost perfection, instead using local plants to enhance the inherent qualities of the existing landscape. This integrated landscape extends into the town of Muskau with green passages that formed urban parks framing areas for development. The town thus became a design component in a utopian landscape. The site also features a reconstructed castle, bridges and an arboretum.

It covers almost 600km of the whole Roman Empire’s Danube frontier. The property formed part of the much large frontier of the Roman Empire that encircled the Mediterranean Sea. The Danube Limes (Western Segment) reflects the specificities of this part of the Roman Frontier through the selection of sites that represent key elements from roads, legionary fortresses and their associated settlements to small forts and temporary camps, and the way these structures relate to local topography. 

Following the left bank of the Lower Rhine River for approximately 400 km from the Rhenish Massif in Germany to the North Sea coast in the Netherlands, the transnational property consist of 102 components from one section of the frontiers of the Roman Empire, which in the 2nd century CE, stretched across Europe, the Near East, and North Africa, over 7,500 km. The property comprises military and civilian sites and infrastructure that marked the edge of Lower Germany from the 1st to 5th centuries CE. Archaeological remains in the property include legionary fortresses, forts, fortlets, towers, temporary camps, roads, harbours, a fleet base, a canal and an aqueduct, as well as civilian settlements, towns, cemeteries, sanctuaries, an amphitheatre, and a palace. Almost all of these archaeological remains are buried underground. Waterlogged deposits in the property have enabled a high degree of preservation of both structural and organic materials from the Roman periods of occupation and use.

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom).

They bear witness to the international European spa culture that developed from the early 18th century to the 1930s, leading to the emergence of grand international resorts that impacted urban typology around ensembles of spa buildings such as baths, kurhaus and kursaal (buildings and rooms dedicated to therapy), pump rooms, drinking halls, colonnades and galleries designed to harness the natural mineral water resources and to allow their practical use for bathing and drinking. Related facilities include gardens, assembly rooms, casinos, theatres, hotels and villas, as well as spa-specific support infrastructure. These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.

Founded, according to legend, by Romulus and Remus in 753 BC, Rome was first the centre of the Roman Republic, then of the Roman Empire, and it became the capital of the Christian world in the 4th century. The World Heritage site, extended in 1990 to the walls of Urban VIII, includes some of the major monuments of antiquity such as the Forums, the Mausoleum of Augustus, the Mausoleum of Hadrian, the Pantheon, Trajan’s Column and the Column of Marcus Aurelius, as well as the religious and public buildings of papal Rome.

The Fertö/Neusiedler Lake area has been the meeting place of different cultures for eight millennia. This is graphically demonstrated by its varied landscape, the result of an evolutionary symbiosis between human activity and the physical environment. The remarkable rural architecture of the villages surrounding the lake and several 18th- and 19th-century palaces adds to the area’s considerable cultural interest.

Chosen from the work of Le Corbusier, the 17 sites comprising this transnational serial property are spread over seven countries and are a testimonial to the invention of a new architectural language that made a break with the past. They were built over a period of a half-century, in the course of what Le Corbusier described as “patient research”. The Complexe du Capitole in Chandigarh (India), the National Museum of Western Art, Tokyo (Japan), the House of Dr Curutchet in La Plata (Argentina) and the Unité d’habitation in Marseille (France) reflect the solutions that the Modern Movement sought to apply during the 20th century to the challenges of inventing new architectural techniques to respond to the needs of society. These masterpieces of creative genius also attest to the internationalization of architectural practice across the planet.

Founded, according to legend, by Romulus and Remus in 753 BC, Rome was first the centre of the Roman Republic, then of the Roman Empire, and it became the capital of the Christian world in the 4th century. The World Heritage site, extended in 1990 to the walls of Urban VIII, includes some of the major monuments of antiquity such as the Forums, the Mausoleum of Augustus, the Mausoleum of Hadrian, the Pantheon, Trajan’s Column and the Column of Marcus Aurelius, as well as the religious and public buildings of papal Rome.

Rhaetian Railway in the Albula / Bernina Landscapes, brings together two historic railway lines that cross the Swiss Alps through two passes. Opened in 1904, the Albula line in the north western part of the property is 67 km long. It features an impressive set of structures including 42 tunnels and covered galleries and 144 viaducts and bridges. The 61 km Bernina pass line features 13 tunnels and galleries and 52 viaducts and bridges. The property is exemplary of the use of the railway to overcome the isolation of settlements in the Central Alps early in the 20th century, with a major and lasting socio-economic impact on life in the mountains. It constitutes an outstanding technical, architectural and environmental ensemble and embodies architectural and civil engineering achievements, in harmony with the landscapes through which they pass.

This serial property of 111 small individual sites encompasses the remains of prehistoric pile-dwelling (or stilt house) settlements in and around the Alps built from around 5000 to 500 B.C. on the edges of lakes, rivers or wetlands. Excavations, only conducted in some of the sites, have yielded evidence that provides insight into life in prehistoric times during the Neolithic and Bronze Age in Alpine Europe and the way communities interacted with their environment. Fifty-six of the sites are located in Switzerland. The settlements are a unique group of exceptionally well-preserved and culturally rich archaeological sites, which constitute one of the most important sources for the study of early agrarian societies in the region.

This property consists of 6 components of defence works in Italy, Croatia and Montenegro, spanning more than 1,000 km between the Lombard region of Italy and the eastern Adriatic Coast. The fortifications throughout the Stato da Terra protected the Republic of Venice from other European powers to the northwest and those of the Stato da Mar protected the sea routes and ports in the Adriatic Sea to the Levant. They were necessary to support the expansion and authority of the Serenissima. The introduction of gunpowder led to significant shifts in military techniques and architecture that are reflected in the design of so-called alla moderna / bastioned, fortifications, which were to spread throughout Europe.

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom). All of these towns developed around natural mineral water springs. They bear witness to the international European spa culture that developed from the early 18th century to the 1930s, leading to the emergence of grand international resorts that impacted urban typology around ensembles of spa buildings such as baths, kurhaus and kursaal (buildings and rooms dedicated to therapy), pump rooms, drinking halls, colonnades and galleries designed to harness the natural mineral water resources and to allow their practical use for bathing and drinking. Related facilities include gardens, assembly rooms, casinos, theatres, hotels and villas, as well as spa-specific support infrastructure. These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.

The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause. The original arc consisted of 258 main triangles with 265 main station points. The listed site includes 34 of the original station points, with different markings, i.e. a drilled hole in rock, iron cross, cairns, or built obelisks.

Human habitation of this elongated sand dune peninsula, 98 km long and 0.4-4 km wide, dates back to prehistoric times. Throughout this period it has been threatened by the natural forces of wind and waves. Its survival to the present day has been made possible only as a result of ceaseless human efforts to combat the erosion of the Spit, dramatically illustrated by continuing stabilisation and reforestation projects.

This serial property combines 28 sites, located in Bosnia and Herzegovina, western Serbia, western Montenegro and central and southern Croatia, representing these cemeteries and regionally distinctive medieval tombstones, or stećci. The cemeteries, which date from the 12th to 16th centuries CE, are laid out in rows, as was the common custom in Europe from the Middle Ages. The stećci are mostly carved from limestone. They feature a wide range of decorative motifs and inscriptions that represent iconographic continuities within medieval Europe as well as locally distinctive traditions.

The transnational serial property is an Enlightenment experiment in social reform. These cultural landscapes demonstrate an innovative, highly influential 19th-century model of pauper relief and of settler colonialism, which today is known as an agricultural domestic colony. The property encompasses four Colonies of Benevolence in three component parts: Frederiksoord-Wilhelminaoord and Veenhuizen in the Netherlands, and Wortel in Belgium. Together they bear witness to a 19th century experiment in social reform, an effort to alleviate urban poverty by establishing agricultural colonies in remote locations. Established in 1818, Frederiksoord (the Netherlands) is the earliest of these Colonies and home to the original headquarters of the Society of Benevolence, an association which aimed to reduce poverty at the national level. The other component parts were constructed between 1820 and 1823. In Frederiksoord-Wilhelminaoord, small farms along planted avenues were built for families and this Colony was referred to as ‘free’. Wortel is a hybrid Colony, first built for families and called ‘free’, later inhabited by beggars and vagrants and catalogued as ‘unfree’. In Veenhuizen large dormitory structures and larger centralized farms along planted avenues were built for orphans, beggars and vagrants that worked under the supervision of guards. This colony was called ‘unfree’. Each component part has a distinctive spatial character, connected to the target group for which it was built, and a specific organization of the work, with either family farms or institutions with working farms for groups of individuals. The Colonies were designed as panoptic settlements along orthogonal lines. They feature residential buildings, farm houses, churches and other communal facilities. At their peak in the mid-19th century, over 11,000 people lived in such Colonies in the Netherlands. In Belgium their number peaked at 6,000 in 1910.

Following the left bank of the Lower Rhine River for approximately 400 km from the Rhenish Massif in Germany to the North Sea coast in the Netherlands, the transnational property consist of 102 components from one section of the frontiers of the Roman Empire, which in the 2nd century CE, stretched across Europe, the Near East, and North Africa, over 7,500 km. The property comprises military and civilian sites and infrastructure that marked the edge of Lower Germany from the 1st to 5th centuries CE. Archaeological remains in the property include legionary fortresses, forts, fortlets, towers, temporary camps, roads, harbours, a fleet base, a canal and an aqueduct, as well as civilian settlements, towns, cemeteries, sanctuaries, an amphitheatre, and a palace. Almost all of these archaeological remains are buried underground. Waterlogged deposits in the property have enabled a high degree of preservation of both structural and organic materials from the Roman periods of occupation and use.

This site is an extensive Inca communication, trade and defence network of roads covering 30,000 km. Constructed by the Incas over several centuries and partly based on pre-Inca infrastructure, this extraordinary network through one of the world’s most extreme geographical terrains linked the snow-capped peaks of the Andes – at an altitude of more than 6,000 m – to the coast, running through hot rainforests, fertile valleys and absolute deserts. It reached its maximum expansion in the 15th century, when it spread across the length and breadth of the Andes. The Qhapac Ñan, Andean Road System includes 273 component sites spread over more than 6,000 km that were selected to highlight the social, political, architectural and engineering achievements of the network, along with its associated infrastructure for trade, accommodation and storage, as well as sites of religious significance.

A landscaped park of 559.9 ha astride the Neisse River and the border between Poland and Germany, it was created by Prince Hermann von Puckler-Muskau from 1815 to 1844. Blending seamlessly with the surrounding farmed landscape, the park pioneered new approaches to landscape design and influenced the development of landscape architecture in Europe and America. Designed as a ‘painting with plants’, it did not seek to evoke classical landscapes, paradise, or some lost perfection, instead using local plants to enhance the inherent qualities of the existing landscape. This integrated landscape extends into the town of Muskau with green passages that formed urban parks framing areas for development. The town thus became a design component in a utopian landscape. The site also features a reconstructed castle, bridges and an arboretum.

Situated in the eastern fringe of Central Europe, the transnational property numbers a selection of sixteen tserkvas (churches). They were built of horizontal wooden logs between the 16^th and 19^th centuries by communities of Orthodox and Greek Catholic faiths. The tserkvas bear testimony to a distinct building tradition rooted in Orthodox ecclesiastic design interwoven with elements of local tradition, and symbolic references to their communities’ cosmogony.  The tserkvas are built on a tri-partite plan surmounted by open quadrilateral or octagonal domes and cupolas. Integral to tserkvas are iconostasis screens, interior polychrome decorations, and other historic furnishings. Important elements of some tserkvas include wooden bell towers, churchyards, gatehouses and graveyards.

The two Prehistoric Rock Art Sites in the Côa Valley (Portugal) and Siega Verde (Spain) are located on the banks of the rivers Agueda and Côa, tributaries of the river Douro, documenting continuous human occupation from the end of the Paleolithic Age. Hundreds of panels with thousands of animal figures (5,000 in Foz Côa and around 440 in Siega Verde) were carved over several millennia, representing the most remarkable open-air ensemble of Paleolithic art on the Iberian Peninsula.

Côa Valley and Siega Verde provide the best illustration of the iconographic themes and organization of Paleolithic rock art, using the same modes of expression in caves and in the open air, thus contributing to a greater understanding of this artistic phenomenon. Together they form a unique site of the prehistoric era, rich in material evidence of Upper Paleolithic occupation.

The site consists of four large groups of stone circles that represent an extraordinary concentration of over 1,000 monuments in a band 100 km wide along some 350 km of the River Gambia. The four groups, Sine Ngayène, Wanar, Wassu and Kerbatch, cover 93 stone circles and numerous tumuli, burial mounds, some of which have been excavated to reveal material that suggest dates between 3rd century BC and 16th century AD. Together the stone circles of laterite pillars and their associated burial mounds present a vast sacred landscape created over more than 1,500 years. It reflects a prosperous, highly organized and lasting society.

It covers almost 600km of the whole Roman Empire’s Danube frontier. The property formed part of the much large frontier of the Roman Empire that encircled the Mediterranean Sea. The Danube Limes (Western Segment) reflects the specificities of this part of the Roman Frontier through the selection of sites that represent key elements from roads, legionary fortresses and their associated settlements to small forts and temporary camps, and the way these structures relate to local topography. 

This serial property of 111 small individual sites encompasses the remains of prehistoric pile-dwelling (or stilt house) settlements in and around the Alps built from around 5000 to 500 B.C. on the edges of lakes, rivers or wetlands. Excavations, only conducted in some of the sites, have yielded evidence that provides insight into life in prehistoric times during the Neolithic and Bronze Age in Alpine Europe and the way communities interacted with their environment.

The property includes the mining sites of Almadén (Spain), where mercury (quicksilver) has been extracted since antiquity, and Idrija (Slovenia), where mercury was first found in AD1490. The Spanish property includes buildings relating to its mining history, including Retamar Castle, religious buildings and traditional dwellings. The site in Idrija notably features mercury stores and infrastructure, as well as miners’ living quarters, and a miners’ theatre. The sites bear testimony to the intercontinental trade in mercury which generated important exchanges between Europe and America over the centuries. Together they represent the two largest mercury mines in the world, operational until recent times.

The Zarafshan-Karakum Corridor is a key section of the Silk Roads in Central Asia that connects other corridors from all directions. Located in rugged mountains, fertile river valleys, and uninhabitable desert, the 866-kilometre corridor runs from east to west along the Zarafshan River and further southwest following the ancient caravan roads crossing the Karakum Desert to the Merv Oasis. Channelling much of the east-west exchange along the Silk Roads from the 2nd century BCE to the 16th century CE, a large quantity of goods was traded along the corridor. People travelled, settled, conquered, or were defeated here, making it a melting pot of ethnicities, cultures, religions, sciences, and technologies.

The Koutammakou landscape in north-eastern Togo and neighbouring Benin is home to the Batammariba, whose remarkable mud tower-houses are known as takienta (sikien in the plural). Nature is strongly associated with the rituals and beliefs of society here. The landscape is exceptional due to the architecture of the tower-houses which reflect the social structure; its farmland and forest; and the associations between people and landscape. The buildings are grouped in villages, which also include ceremonial spaces, springs, sacred rocks and sites reserved for initiation ceremonies.

The ‘Roman Limes’ represents the border line of the Roman Empire at its greatest extent in the 2nd century AD. It stretched over 5,000 km from the Atlantic coast of northern Britain, through Europe to the Black Sea, and from there to the Red Sea and across North Africa to the Atlantic coast. The remains of the Limes today consist of vestiges of built walls, ditches, forts, fortresses, watchtowers and civilian settlements. Certain elements of the line have been excavated, some reconstructed and a few destroyed. The two sections of the Limes in Germany cover a length of 550 km from the north-west of the country to the Danube in the south-east. The 118-km-long Hadrian’s Wall (UK) was built on the orders of the Emperor Hadrian c. AD 122 at the northernmost limits of the Roman province of Britannia. It is a striking example of the organization of a military zone and illustrates the defensive techniques and geopolitical strategies of ancient Rome. The Antonine Wall, a 60-km long fortification in Scotland was started by Emperor Antonius Pius in 142 AD as a defense against the “barbarians” of the north. It constitutes the northwestern-most portion of the Roman Limes.

The Moravian Church Settlements is a transnational serial extension of Christiansfeld, a Moravian Church Settlement (Denmark), already inscribed on the World Heritage List. The extension includes three municipalities founded in the 18th century: Herrnhut (Germany), Bethlehem (United States of America), and Gracehill (United Kingdom of Great Britain and Northern Ireland). Each settlement has its own architectural character based on ideals of the Moravian Church but adapted to local conditions. Together, they represent the transnational scope and consistency of the international Moravian community as a global network. There is an active congregation present in each component part, where traditions are continued and constitute a living Moravian heritage.

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom). All of these towns developed around natural mineral water springs. They bear witness to the international European spa culture that developed from the early 18th century to the 1930s, leading to the emergence of grand international resorts that impacted urban typology around ensembles of spa buildings such as baths, kurhaus and kursaal (buildings and rooms dedicated to therapy), pump rooms, drinking halls, colonnades and galleries designed to harness the natural mineral water resources and to allow their practical use for bathing and drinking. Related facilities include gardens, assembly rooms, casinos, theatres, hotels and villas, as well as spa-specific support infrastructure. These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.
