The old citadel (in Greek Palaio Frourio) is an old Venetian fortress built on an artificial islet with fortifications surrounding its entire perimeter, although some sections, particularly on the east side, are slowly being eroded and falling into the sea. Nonetheless, the interior has been restored and is in use for cultural events, such as concerts and Sound and Light Productions, when historical events are recreated using sound and light special effects. These events take place amidst the ancient fortifications, with the Ionian sea in the background. The central high point of the citadel rises like a giant natural obelisk complete with a military observation post at the top, with a giant cross at its apex; at the foot of the observatory lies St. George’s church, in a classical style punctuated by six Doric columns as opposed to the Byzantine architectural style of the greater part of Greek Orthodox churches.
