Istanbul City Walls (Walls of Constantinople)

The Istanbul City Walls, also known as the Walls of Constantinople, were constructed in the fourth and fifth centuries to protect the city. Stretching around the Old City peninsula, these defensive structures played a crucial role until they were breached in 1453 during the Ottoman conquest. Today, many sections have been restored and seamlessly integrate with the bustling historical neighborhoods. Visitors can walk along these ancient walls, experiencing the blend of history and modern life that characterizes Istanbul.
