The fortress is situated on the Asian shore of the Bosphorus, the sole outlet of the Black Sea, and it was built by Sultan Bayezid in 1390-91. Next to it there is a stream running into the sea.

Together with the Rumeli Fortress on the opposite side, it ensured full control over the traffic in the Bosphorus. This small fortress creates a picturesque scene with the old wooden houses leaning on its walls and its green surroundings. The Kanhca district, a little further up the Bosphorus, is famous for its seaside cafes and yogurt. The Asian towers of the Fatih Bridge rises in this district.
