Ebu İshak Mosque

Ebu İshak Mosque, formally the Ebu İshak Kazeruni Mosque, was built in Bursa in the late 14th century by Sultan Yıldırım Bayezid as part of a dervish lodge (zaviye) dedicated to Sheikh Ebu İshak Kazeruni, a Persian clergyman who died in 1035 and founded the Kazeruniye dervish order. The inscription panel over the entrance records both its original construction under Bayezid I and a later restoration dated 1479 carried out under Mehmed the Conqueror. The building consists of a five-bay domed entrance portico leading into a domed central hall with a raised, vaulted eyvan on the south side housing the mihrab, flanked by two barrel-vaulted rooms. It originally formed part of a larger charitable complex including a soup kitchen and a school, of which only the mosque and an attached mausoleum survive. Further repairs are recorded in 1655, 1760, 1764, 1844 and 1882, with a final restoration in 1969 carried out by the Bursa Society of Friends of Ancient Monuments.
