Theodosian Walls

The Theodosian Walls are a series of impressive fortifications constructed in the 5th century around Constantinople (modern-day Istanbul) by the Roman Emperor Theodosius II. These walls were designed to protect the city from invasions and were notable for their height and thickness, featuring a double line of defense with towers and a wide moat. The walls successfully defended Constantinople for over 1,000 years, until the city fell to the Ottoman Turks in 1453. Today, they stand as a significant historical monument, showcasing the architectural prowess of the Byzantine Empire and highlighting the city's strategic importance in history.
