Roman Emperor Theodosius II built a triple wall from the Golden Horn to the Sea of Marmara, fortifying the landward side of Constantinople with a very strong barrier. The walls took over 30 years to build, being built between 413 and 447. On the far side of the defenses was a moat, sixty feet wide and twenty-two feet deep, which the enemy would have to cross in order simply to reach the first wall. Behind the low first wall, crouching archers could securely pick off attackers. If the moat was passed and the first wall breached, there were two additional walls: the middle wall was twenty-seven feet tall, and the third wall was seventy feet tall; from the third, the defenders could shoot their arrows and catapult their stones. These walls protected Constantinople from invasion for a millennium, until 1453, by which time a new invention, the cannon, could pierce the walls. The ruins are still impressive over 1,500 years later.
