Sivrihisar Grand Mosque () is a historical mosque in Sivrihisar, Turkey.
The mosque is located in Sivrihisar ilçe (district) of Eskià Âehir Province. It was built by Leà Âker Emir Celaleddin Ali in 1231âÂÂ1232 during the reign of Anatolian Seljuk Sultan Kayqubad I (r. 1220âÂÂ1237). It saw later two restorations, in 1275 by Eminüddin Mikail bin Abdullah, the regent of Kaykhusraw III (r. 1265âÂÂ1284), and in 1440 by Hñzñr Bey, a judge in Sivrihisar and later the first judge in Istanbul. The mosque is a rare example of wooden-columned architectural technique in Anatolia together with four others.
The ground area of the mosque is . 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 in the inside, of which upper parts are decorated by painted 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 Ballñhisar today close to Sivrihisar. There are six naves in east-west direction. The middle naves are higher than the others resembling the historic Turkic tents used in the nomadic era the Central Asia. The mosque's minbar, the pulpit, is a masterwork made by Horasanlñ ðbni Mehmet in 1245, and is famous for its ornaments in geometrical and floral design engraved in walnut wood. It is believed that the minbar was brought here from the Sivrihisar Kñlñç Masjid, which was demolished in 1924. The minaret was added by Osman oÃÂlu Hacñ Habib in 1409âÂÂ1410 according to its inscription.
