Yedikule Fortress walls and towers rising above the Bosphorus in Istanbul

8 historic sites

Castles in Turkey

Istanbul sits at the crossroads of two continents — and its European shore (Thrace) contains some of the most extraordinary military architecture in history. The Theodosian Walls, built in 412 AD and unconquered for a thousand years, are the defining land fortification of the ancient world. Yedikule Fortress, Rumeli Hisarı on the Bosphorus, and the ruins of the Blachernae Palace trace the full arc of the city’s story from Roman capital to Ottoman empire.
