The story of Alâeddin Sinop Mosque

Pieces of this mosque's pulpit now sit not in Sinop but in the Tiled Kiosk in Istanbul. Named after the Seljuk sultan Alaeddin Keykubad I and also called the "Ulu Cami", it is the largest Seljuk mosque in Northern Anatolia. It follows the oldest mosque type, the so-called "Arab mosques": transverse naves suited to long rows of worshippers and a wide courtyard.

Its origins are uncertain, but it was very probably destroyed in the 1261 attack by the Komnenoi of Trebizond and rebuilt on the old foundations in 1268 by Pervane Muineddin; its oldest inscription dates from 1268. In 1376 Candaroğlu Celaleddin Bayezid Bey carried out a major repair, adding the Candarid tomb in the courtyard's northeast corner. An inscription of 1430 credits the mihrab and pulpit to İsfendiyar Bey. That pulpit, praised by Evliya Çelebi, was wrecked when the dome collapsed in the 1853 earthquake.

The mosque was last restored in 2008–2009.
