Cankurtaran, 34122 Fatih/İstanbul, TurkeyThe Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople since its founding as the new capital of the Roman Empire by Constantine the Great.
Constantinople’s great city walls were breached only twice in 1600 years. The 5th-century city walls built by Emperor Theodosius II stretch for 6.5 km (4 miles) from Istanbul’s Golden Horn to the Sea of Marmara.
You can admire them at many points in Istanbul(especially the several gates in the walls), but it’s easiest to combine a view of the walls with a visit to the Kariye Museum (Chora Church) and the nearby Byzantine palace of Tekfur Saray (Palace of Constantine Porphyrogenetus) in the Edirnekapı (Edirne Gate) district. Another good vantage point, relatively easy to reach, is Yedikule, the Fortress of the Seven Towers.
