Sivrihisar Grand Mosque

Sivrihisar Grand Mosque (Sivrihisar Ulu Camii) is a historic mosque in Sivrihisar, Turkey. The mosque is located in Sivrihisar ilçe (district) of Eskişehir Province. It was built by Leşker Emir Celaleddin Ali in 1231–1232 during the reign of Anatolian Seljuk Sultan Kayqubad I (r. 1220–1237). It later underwent two restorations, in 1275 by Eminüddin Mikail bin Abdullah, the regent of Kaykhusraw III (r. 1265–1284), and in 1440 by Hızır Bey, a judge in Sivrihisar and later the first judge in Istanbul. The mosque is one of only five examples of wooden-columned architectural technique in Anatolia. The ground area of the mosque is 1,485 m2 (15, 980 sq ft). It has a rectangular plan. The outer walls are of ashlar. It has four entrances. Marble inscriptions showing the historical restoration dates are found on the northern and eastern gates. The roof is covered by tiles, which were replaced by lead sheet not long ago. The roof is carried by 67 wooden columns, of which upper parts are decorated by, mostly in green, red and black colors, engravings of traditional figures. Some columns stand on stone base having ancient column head. It is likely that the stone columns heads originate from Pessinus, an ancient city known as Ballıhisar today close to Sivrihisar. There are six naves in east-west direction. The middle naves are higher than the others resembling the historic Turkic ten
