The New Fortress standing on top of St. Mark Hill defines the western boarder of Corfu’s Old Town. This view from the port clearly shows its two levels. The lower bastion wall was built by the Venetians during the 16th century. It withstood an attack by 8,000 Ottoman Turks in 1716.The structures on top were added during the British Protectorate period (1815-1864). Although many of these defenses were demolished in 1864 when Corfu became a Greek island, the Fortezza Nuova remains an exciting, historic structure to explore.
