A little town on the coast of a wonderful lake of Askania, Iznik (Nicaea) is well-known because the first Ecumenical Council took place here in 325 AD. The Council of Nicaea was historically significant because it was the first effort to attain consensus in the church through an assembly representing all of Christendom. It was the first occasion for the development of technical Christology. This town had even been the temporary capitol of the Byzantine Empire when Constantinople was captured by the Latins. The centre of the town, still surrounded by Roman and Byzantine walls, is remarkable for the ruins of St. Sophia Temple remaining since those times. In addition to that, an interesting monument is the Green Mosque, decorated by light blue ceramics.
