[4] In the aftermath of the first great Ottoman siege of Corfu in 1537, the Venetians developed plans to expand the fortifications of the city.

[2][5] To achieve their goals the Venetians razed 2,000 homes in the suburb of San Rocco, and built new fortifications and walls in their place at great expense.

Its western side features a dry moat which spans the length of the walls, running from the vegetable market to the new harbour.

[2][9] The structure features twin bastions, named Skarponas and Epta Anemoi ("Seven Winds"),[10] which has a commanding view of the sea and the mountains of mainland Greece.

Both captains were sworn before the Senate and part of their oath was to never communicate with each other during their two-year tenure as governors of the fortresses.

It displays the Lion of Saint Mark (the symbol of Venice) and the arms of Diedo[13] below which is the following Latin inscription: ("To God, the most good and greatest, Alvise III Mocenigo, Duke of the Venetians (i.e. Doge of Venice); Marco Antonio Diedo, Supreme Governor, Giorgio Grimani, Commander of the Fleet; the first ordered this (i.e. the wall); the second planned it; the third, by labour day and night, quickly completed it, in the year of our Lord 1728").

When the latter fort was demolished, the explosion was so strong that it broke house windows on the Corfu side of the sea channel.
