The Grand Mosque

“Ulu Cami” (The Grand Mosque) was built by Yıldırım Bayezid between 1396 and 1399. After the victory at Nicopolis (Niğbolu) in 1396, Yıldırım Bayezid wanted to built 20 masjids in Bursa, but on suggestion of Emir Sultan, his son-in-law and one of the period’s important scolar men, he built only one, the “Ulu Cami”, or Grand Mosque, covering it with 20 domes.
