Explanation: Constantinople endured for more than 1,100 years as the Byzantine capital in large part due to the protective wall completed under Theodosius II in 413. Expanding the city perimeter west from Constantine's wall by approximately a mile, the new one stretched 3-1/2 miles from the Sea of Marmara to the Golden Horn.
