The Old Fortress of Corfu is one of the most impressive fortification projects in Europe. It is the first place to capture your eyesight, as the ferry approaches Corfu. It stands on the eastern side of the town, on a rocky peninsula that spreads into the sea.

This fortress is called Old in contrast to the New Fortress (of Saint Mark), that was also built to protect the town from enemies and pirates.

This fortress was constructed by the Venetians in the 15th century on the site of a former Byzantine castle.
