The Green Mosque, or Yeşil Camii, was built in the 1380s and is one of Iznik's finest Ottoman monuments. Its tiled minaret gives the mosque its name: green, turquoise, and blue surfaces rising above the quieter stonework below.
The building was damaged during the war of 1920 and restored in the 1960s. It is a good place to see how early Ottoman architecture in Iznik absorbed Byzantine surroundings while developing its own style.
