The Old fortress.
During its turbulent history Corfu needed to entrench it self against its conquerors. In the beginning of the 8th century BC the Byzantines built the first walls and the first moat, the "Contra Fosa", which separates the fortress from the city. In the 16th century, the Venetians, fearing a Turkish attack, extended the bulwark and the moat, creating a second and a third line of defense.
The bare rocks around the hills made the fortress impenetrable, which is a masterpiece of architectural art. While on the other hand, it offers the visitor an incredible view to the city, the sea ford up across the land and the hills of Epirus. Worth visiting inside the fortress is the chapel of Saint George, which was built by the British in 1840.
