Sivrihisar Great Mosque is located in Sivrihisar county of Eskişehir province. Mosque was built by Leşker Emir Celaleddin Ali in 1231-1232. The building subsequently was restored by Mikail bin Abdullah (Governor of Anatolian Seljuk Empire) in 1275 and then by Hızır Bey (Judge of Sivrihisar) in 1440.
This structure is in the group of the wooden columned and roofed mosques in Anatolia. Wooden columned and roofed mosques are not prevalent in Anatolian Turkish Architecture. Sivrihisar Great Mosque represents this rare architectural technique with other important buildings such as Eşrefoğlu Mosque (inscribed on the UNESCO Tentative List in 2011), Mahmut Bey Mosque (inscribed on the UNESCO Tentative List in 2014), Afyon Great Mosque and Arslanhane Mosque in Ankara.
This mosque’s plan scheme is rectangular and exterior walls are constructed by hewn stone. The mosque has four entrance doors and the roof carried by 67 wooden pillars. On the upper parts of these pillars are decorated by engravings, relieves and traditional ornament technique called as “Kalem işi”. This name comes from the applying ornaments on wood surfaces by special brushes named “Kalem”. Before painting the figures, contours of figures designed over the small punched papers. The artists used coal powder to draw geometrical and floral decoration. Kalem işi ornaments on wooden surfaces in Sivrihisar Great Mosque are mostly in green, red and black colours. Some of wooden pillars stands on stone bases and have ancient marble column heads. It is believed that these columns were brought from the Pessinus Ancient City, close to Sivrihisar county.
The building has six naves in East-West direction and middle naves are higher than the others. This architectural design reminds the shape of ancient Turkish tents from the nomadic era in the Central Asia.
Sivrihisar Great Mosque is famous for its delicately decorated wooden pulpit as well. Pulpit was made by walnut and decorated by geometrical and floral ornaments.
Justification de la Valeur Universelle Exceptionnelle
Sivrihisar Great Mosque with its all the main elements, is an outstanding example of early Anatolian Turkish architecture. It is one of the most important examples of wooden columned and roofed mosques in Anatolia. This rare structure technique increases the importance of Sivrihisar Great Mosque. Although its exterior appearance is plain, its interior full of beautiful delicate decorated wooden ceiling, floor and columns.
There are several wooden columned and roofed mosques in Anatolia such as Eşrefoğlu Mosque, Afyon Great Mosque, Mahmut Bey Mosque and Arslanhane Mosque. But as compared with the others, it is possible to state that the Sivrihisar Great Mosque draws attention with its large-size and the good condition of ornaments on wooden surfaces. Nevertheless, with its delicate work the wooden pulpit is one of important elements of Sivrihisar Great Mosque.
The roof carried by 67 wooden pillars and this number symbolizes the sum of the age of Prophet Mohammed when he died (63) and the number of his Caliphs (4).
Criterion (ii): Wooden columned and roofed mosques are rare type in Anatolian Turkish Architecture. Sivrihisar Great Mosque is one of the elegant examples of this kind of structures. Before coming to Anatolia, Turkish architects used brick and terra cota as building materials. After settled down in Anatolia, they turned to prefer stone instead of brick and terra cota.
But during the Anatolian Seljuks era and later on Turkish architects rarely used wood as a building material especially interior of buildings to carry roof. Wood was a traditional construction material in Central Asia where the seeds of Turkish Architecture were sown. Turkic nomad communities used wood to build their tents named “Oba”.
When we take into consideration the building date, it is possible to propose that the Sivrihisar Great Mosque bears this Central Asian structural building character and symbolizes the transmitting of a life style of Anatolia.
