Yedikule Fortress

The story of Yedikule Fortress begins long before the Ottoman era, rooted in the late Roman period. Originally, the site featured the Golden Gate (Porta Aurea), a magnificent triumphal arch built by Emperor Theodosius II in the 5th century. This triple-arched gate, clad in polished marble and adorned with gilded statues, served as the primary ceremonial entrance for Byzantine emperors returning from victorious military campaigns. It was integrated into the massive Theodosian Walls, representing the pinnacle of Roman engineering and imperial grandeur. Following the Ottoman conquest of Constantinople in 1453, Sultan Mehmed the Conqueror recognized the strategic importance of the site. In 1458, he ordered the construction of three additional towers, connecting them with heavy curtain walls to the existing four Byzantine towers, thus creating the 'Fortress of the Seven Towers.' Initially, the fortress served as the Ottoman Empire's central treasury and archive, housing the state's most precious jewels, gold, and historical documents under heavy guard within its impenetrable stone walls. Over the following centuries, Yedikule’s function shifted from a treasury to a notorious state prison. It became the place where high-ranking political prisoners, including fallen grand viziers and foreign ambassadors, were held during times of war or political turmoil. One of its most tragic moments occurred in 1622 with the execution of the young Sultan Osman II. Today, the fortress stands as a hauntingly beautiful museum, offering visitors a chance to walk the ramparts and witness the complex layers of Istanbul’s Roman, Byzantine, and Ottoman past.
