The Walls of Constantinople are a series of defensive stone fortifications that have protected the city since its founding as the new Roman capital by Constantine the Great. Initially constructed on all sides to guard against both sea and land attacks, the walls were substantially expanded in the 5th century with the famous double line of the Theodosian walls, creating one of antiquity's most complex and elaborate fortification systems. Though sections varied in elaboration, the walls proved nearly impregnable when properly manned, successfully defending the city and Byzantine Empire through numerous sieges by the Avar–Sassanian coalition, Arabs, Rus', and Bulgars. The fortifications retained strategic value even after the introduction of gunpowder cannons, though Ottoman forces breached them during the 1453 siege. Largely maintained through the Ottoman period, sections were dismantled in the 19th century as the city expanded beyond its medieval boundaries. Despite centuries of neglect, substantial portions survive standing today, with large-scale restoration efforts underway since the 1980s.
