Istanbul is famous for its ramparts, fortresses and towers as well. Some of these were used for non-defence aims after the conquest of Istanbul, and also couldn't be saved because of suffering rack and ruin from the effects of centuries.
However, Rumeli Fortress built a year before the conquest, stands with its all grandeur. The ownership seal that the Turks put on the Bosphorus shore stays in excellent condition as an indelible seal.
