How long were the walls around Constantinople?

Answer 1

The walls around Constantinople, known as the Theodosian Walls, extended approximately 22 miles (35 kilometers) in length. Constructed in the 5th century, they included a series of double walls with a moat and were designed to protect the city from invasions. The walls were among the most formidable fortifications of their time, contributing significantly to the city's defense for centuries. They remained largely intact until the fall of Constantinople in 1453.
