Grand Mosque or Ulu Cami seen at night behind a busy road, built 1396-99 under the Ottoman Sultan Bayezid I by the architect Ali Neccar in the Seljuk style, Bursa, Turkey. It is a large rectangular building with 2 minarets, and 20 domes supported by 12 columns. Supposedly the 20 domes were built instead of the 20 separate mosques which Sultan Bayezid I had promised for winning the Battle of Nicopolis in 1396. The mosque is in the old city centre of Bursa and remains the largest mosque in the city. Picture by Manuel Cohen
