Çimenlik Fortress (Kale-i Sultaniye)

Çimenlik Fortress (Kale-i Sultaniye) was constructed in 1462-1463 by Sultan Mehmet the Conqueror for the defense of İstanbul as one of the two fortresses built at the narrowest point of the strait and since then it has become the nucleus of the city. It was restored when necessary and especially in the 19th Century, modern cannon emplacements and armament depots were built after demolishing the western ramparts parallel to the strait. During 1915 Çanakkale Battles, it served as a place for dispatching troops and administration of Central Defense Group.
