Iznik

Iznik is a town and an administrative district in the Province of Bursa, Turkey. It was historically known as Nicaea, from which its modern name also derives. The town lies in a rich bowl at the eastern end of Lake Iznik, limited by scopes of slopes toward the north and south. From point A to point B, the town is just 90 kilometers southeast of Istanbul however by street it is 200 km around the Gulf of Izmit. It is 80 km by street from Bursa. The town is arranged with its west divider ascending from the lake itself, giving both security from attack from that bearing and also a wellspring of provisions which would be hard to cut off.

The lake is sufficiently expansive that it can't be barricaded from the land effectively, and the city was sufficiently vast to make any endeavor to achieve the harbor from shore-based attack weapons extremely difficult. The city was encompassed on all sides by 5 km of dividers around 33 ft high. These were thusly encompassed by a twofold discard on the land parcels, and furthermore included more than 100 towers in different areas. Vast entryways on the three landbound sides of the dividers gave the main access to the city.
