Yedikule Fortress

Yedikule Fortress is a fortified historic structure located in the Yedikule neighbourhood of Fatih, in Istanbul, Turkey.

Built in 1458 on the commission of Ottoman Sultan Mehmed II, the seven-tower complex was created by adding three new towers and fully enclosing a section of the ancient Walls of Constantinople, including the two twin towers that originally constituted the triumphal Golden Gate built by Roman Emperors Theodosius I and Theodosius II.

The fortress came to be known as the home of a formidable royal dungeon that housed notable figures throughout its history, and the associated intrigue captured the public's imagination over the centuries in various legends, stories, and the arts.
