Yedikule Fortress

The Golden Gate was the ceremonial entrance through the Theodosian city walls. After the Ottomans captured the city in 1453, Mehmed II needed a stronghold for his treasures and documents. The gate was therefore bricked up and the walls reinforced into a fortress, with valuables stored in its seven towers, hence yedi kule. In the following century the treasury moved to Topkapi Palace and the fort became a prison for high-level detainees - Osman II was strangled here in 1622. It remained in use until 1837, whereupon the Golden Gate was re-opened.
