Yedikule Fortress

Yedikule Fortress ('Fortress of the Seven Towers') is a historic fort in Istanbul’s Fatih district, built in 1458 by Sultan Mehmed II by enclosing part of the Walls of Constantinople, including the Golden Gate. Originally an imperial treasury, it later became a state prison, housing notable captives like Sultan Osman II and foreign diplomats.

The fortress, located on the Sea of Marmara, featured storage for valuables, a mosque, and garrison quarters. Used as a prison until 1837, it later served as a gunpowder magazine before becoming a museum in 1895. Today, it hosts cultural events and an open-air theater.
