Corfu, New Fortress

Following the 1st Ottoman siege of Corfu, the Venetians recognized that the city had expanded outside of the walls of the old fort leaving it unprotected. So they began construction of the new fort at the other end of town. The main, major fortifications are Venetian, but most of the current structures were built by the British.
The 1st picture looks up the road that approaches a castle gate. This looks to me like a protected supply route from the harbor to the castle to allow resupply by sea.
The 2nd picture looks down the curving tunnel/gate into the fortress. The 3rd picture is in the lower part of the fortress and shows a building from the Venetian times. The 4th picture is the access ramp up to the upper, main part of the fortress. The 5th picture is of the main building at the top level, and the 6th picture is a glance inside the building as it wasn't open.Read more
