The Diaolou Buildings and Villages for Tibetan and Qiang Ethnic Groups are located in the alpine valleys in the east of Qinghai-Tibet Plateau, and include 225 Diaolou buildings and 15 villages distributed in Barkam County, Jinchuan County, Wenchuan County, Li County, and Mao County in Aba Tibetan and Qiang Autonomous Region, and in Kangding (known as Tatsienlu in the Western World) County, Danba County, and Daofu County in Ganzi (known as Garz, or Garze, or Kardze in the Western World) Tibetan Autonomous Region, in Sichuan Province in the upper reaches of the Dadu River and the Min River in the Hengduan Mountains. The nominated property includes: Buwa Diaolou Buildings and Village of Qiang in Wenchuan County, including 6 Diaolou Buildings; Luobo Village of Qiang in Wenchuan County; Taoping Village of Qiang in Li County, including 3 Diaolou Buildings; Heihu Village of Qiang and Yingzuihe Village in Mao County, including 7 Diaolou Buildings; Diaolou Buildings and Tibetan Villages in Danba County, including 151 Diaolou Buildings distributed in Kegeyi Village, Xiarenyi Village, Boselong Village, Han'eyi Village, Zuobi Village, Moluo Village, Dongfeng Village, Gongbu Village, and Jiaju Village; Diaolou Buildings and Tibetan Villages of Zhibo, in Songgang Village and Zhibo Village of Barkam County, including 4 Diaolou Buildings; Group of Diaolou Buildings of Zengda Pass, in Jinchuan County, including 2 Diaolou Buildings; Ancient Diaolou Buildings of Kangding, including 23 Diaolou Buildings in Kangding County; and Ancient Diaolou Buildings of Daofu, including 21 Diaolou Buildings in Daofu County.
The Diaolou buildings are some high watchtowers mostly built with stone, with only a few built of adobe in the areas where Qiang people live. A Diaolou building is usually 10 to 60 meters high and covers an area of 25 to 100 square meters. On each floor, it is designed with openings, floor slabs and a single wooden ladder. There are often embrasures on the exterior wall. Besides the square plan, the floor plans of the Diaolou buildings of Qiang are often in form of equilateral polygons with extra ridges masoned on the outer walls, while the plans of the Diaolou buildings of Tibetan are often star-shaped with 5, 6, 8, 12, or 13 corners. The techniques used in the construction of the Diaolou buildings include the outward masonry, the batteredwall and the use of wooden bars for reinforcement etc., all of which represent the highest level of traditional Chinese stone tower building techniques. The earliest historic document mentioning the Diaolou buildings was the Book of the Later Han written in the 5th Century. However, among extant Diaolou buildings so far, the earliest constructed one dates back to the Tang Dynasty (618-907AD) and the others constructed in later dynasties until the Qing Dynasty (1644-1911AD). The origins of the Diaolou buildings are associated with the nature worship and the defensive demands of the ancestors of Tibetan and Qiang people, with functions of residence, religion, ostentatious display of wealth, and geomancy (Fengshui) emerging later. They finally developed into various types of architecture in combination with folk residences, temples, and military camps (fortresses of tribal leaders).
The residences of the Tibetan and Qiang people are often 2 to 4-storey flat-topped Diaolou buildings with rectangular plans, stone-wood structure and earthen roofs. People rear livestock in pens on the ground floor, live and store on the upper middle floors, and use the top floor as the drying platform. The main living room is equipped with a fireplace and the area of each floor is gradually reduced upwards. White stones are piled up at the four corners of the roof, reflecting the local worship of snowy mountains and white stones.
The villages of Tibetan and Qiang ethnic groups are the agricultural settlements on the plateau, which are usually located on the terraces or gentle slopes between the alpine valleys, abiding by the principles of facing the sun, situated close to water, avoiding the winds, and occupying less arable lands. They are often surrounded with sacred mountains, divine woods, religious and entertaining places. The settlements are diverse in scale, with the different distribution: concentrated, dispersive, or along the mountain ridges. The Diaolou buildings are distributed inside or outside the village or close to the strategically important places according to their various functions. The number of Diaolou buildings varies in different villages, with that of the Tibetan villages relatively larger.
Justification of Outstanding Universal Value
The Tibetan and Qiang ethnic groups, with a long history and rich associations, live together in the areas of the Hengduan Mountains in the east of Qinghai-Tibet Plateau. Their buildings and settlements strongly feature the local and ethnic characteristics due to the influences of their production modes, religious beliefs, plateau landforms, alpine climates, etc. The numerous and extensively distributed Diaolou Buildings and Villages for Tibetan and Qiang Ethnic Groups are represented by those in Aba and Ganzi areas in the west of Sichuan Province.
The architectural tradition of the Diaolou buildings originates from the local stone buildings and tombs in the Neolithic Age. Incorporating religious elements such as the nature worships, Bonpo and Buddhism and meeting the defensive and residential demands, construction techniques and rich forms of vernacular architecture were developed, and Diaolou buildings, the tower-form buildings containing both spiritual and physical functions were erected, representing the unique achievements of the traditional architecture of the Tibetan and Qiang ethnic groups.
The production mode in Tibetan and Qiang areas is mainly farming supplemented by animal husbandry. The locations and layouts of their villages not only manifest the rational use of land and other natural resources, but also express the respect of nature, which create the beautiful landscape and a sustainable relationship between human and land.
The Diaolou Buildings and Villages for Tibetan and Qiang Ethnic Groups display the great adaptability and creativity of the local people, as well as their cultural traditions, in the severe natural environment of the Qinghai- Tibet Plateau, which bear a unique testimony to the Tibetan and Qiang societies and history.
The Diaolou Buildings and Villages for Tibetan and Qiang Ethnic Groups meet World Heritage criteria (i), (ii), (iii), (iv), and(v). In the meantime, in consideration of the backgrounds of the agricultural societies on the plateau and their diversity in ethnic groups, the nominated property fall into the category of the cultural landscape the organically evolved one, which testify the multicultural traditions and their continuity.
Criterion (i): The Diaolou Buildings and Villages for Tibetan and Qiang Ethnic Groups are the masterpiece of architecture created by the local ancestors restrained and inspired by the severe natural environments, which take stone, earth and wood as the constructing materials, and have fulfilled remarkable achievements in the aspects of stability, height and scale of architecture through the unique, sophisticated and consummate techniques. The Diaolou buildings are 60 meters high at maximum, and the largest height-side-length ratio can reach 10:1. The architectural floor plans have patterns of 4, 5, 6, 8, 12, or 13 corners. Of the large number of Diaolou buildings, the spiritual functions such as nature worship and religious beliefs are integrated with the practical residential and defensive functions. In the combination of folk residences, military camps, temples and others, they developed into various types of buildings. Most of the Diaolou buildings survived the Sichuan Earthquake in 2008, which demonstrate their great aseismatic capacity.
Criterion (ii): The forms, functions and techniques of the Diaolou Buildings of Tibetan and Qiang Ethnic Groups and the locations of the villages and their diversity in layout are the results of the inheritance and developments of different ethnic groups in various areas for more than 2000 years, which manifest the diversity of languages, ethnic groups and religions in the Tibetan-Yi Corridor area in Southwest China, and their ethic migrations and cultural evolutions as well, especially the transformation from nomadic to agricultural civilization, and the cultural exchanges and communications between the Tibetan and the Han people.
Criterion (iii): The Diaolou Buildings of Tibetan and Qiang Ethnic Groups reflect the unique local culture that has always emphasized the spiritual connection between the height of architecture and divinity ever since the ancient time. The continuously evolving landscape and its relative intangible heritage constituted by the Diaolou buildings and villages, as evidence to their long history and traditional societies, authentically manifest the cultural features and evolving processes of the agricultural civilization on the Qinghai-Tibet Plateau.
Criterion (iv): The Diaolou buildings, featuring their large scales, sophisticated techniques and various forms, represent the great achievements of the traditional architecture of Tibetan and Qiang ethnic groups, and constitute a unique landscape of agricultural settlements on the Qinghai-Tibet Plateau in combination of such elements as folk residences, temples, farmlands, sacred mountains, sacred trees, valleys, rivers and others, which reflect the complicated social transitions in the Tibetan-Yi Corridor area in the large context of time and space through their rich contents and meanings.
Criterion (v): The locations and layouts of the villages of Tibetan and Qiang ethnic groups manifest multiple functions of defense, disaster prevention and relief, production, religion, providing an outstanding example of human settlements with full respect to the natural laws and an example of the three-dimensional agriculture in vertical climatic zone in the Hengduan Mountains. At present, with the severe challenges of urbanization, energy exploitation, tourism development to the natural environment on the Qinghai-Tibet Plateau and to traditional cultures of Tibetan and Qiang ethnic groups, the lifestyles represented by the Diaolou buildings and villages should be properly protected.

Comparison with other similar properties
In consideration of the association with the nominated villages, the World Heritage sites involved in the comparative study are divided into two groups according to their physical forms: i.e. the vernacular settlements with defensive watchtowers and the traditional defensive settlements, and the other similar settlements of different cultural backgrounds and natural environments: i.e. the agricultural settlement heritage in Asia, and the Arctic Circle cultural landscape in Europe.
The traditional defensive settlements include the Old Walled City of Shibam (1982), and the Old City of Sana'a (1986) in Yemen, and the Historic Centre of San Gimignano in Italy (1990). Firstly, all these three sites are urban historic settlements, while the villages of Tibetan and Qiang ethnic groups are vernacular settlements. Secondly, the towers in these three sites are mainly located within the urban areas and were built in about the 10th Century (Shibam and Sana'a) and the 13th to 14th Century (San Gimignano) respectively. The Diaolou Buildings of Tibetan and Qiang Ethnic Groups feature a larger number and wider distribution area with a continuous history of a thousand years. Thirdly, the buildings in the Old Walled City of Shibam and the Old City of Sana'a are mainly folk residences in the form of towers, and those in the Historic Centre of San Gimignano mainly the defensive watchtowers, all of which perform a single function. In contrast, the Diaolou Buildings of Tibetan and Qiang Ethnic Groups combine both the practical and spiritual functions.
The agricultural settlement heritage sites in Asia include the Historic Villages of Shirakawa-go and Gokayama in Japan (1995), the Ancient Villages in Southern Anhui - Xidi and Hongcun in China (2000), and the Historic Villages of Korea: Hahoe and Yangdong in Korea (2010). All of these mentioned sites are associated with agriculture and wooden architecture, and the Confucian culture and Japanese Shintoism as well. The nominated property, however, features the plateau agriculture, defensive architecture built of stone with characteristics of nature worship, Bonpo, Buddhism and others, and represents the diversity of agricultural civilizations and architectural traditions in Asia.
