İznik is a town and an administrative district in the Province of Bursa, Turkey. It was historically known as Nicaea (Greek: Νίκαια), from which its modern name also derives. The town lies in a fertile basin at the eastern end of Lake İznik, bounded by ranges of hills to the north and south. As the crow flies, the town is only 90 kilometres (56 miles) southeast of Istanbul but by road it is 200 km (124 miles) around the Gulf of Izmit.
