ST Georges Castle
The Venetian Castle of Saint George in Kefalonia: The Castle of Saint George is located 7 km southeast of Argostoli, above the village Peratata Kefalonia. It has a polygonal shape and covers an area of 16,000 sq. m. This Castle was originally built in the 12th century by the Byzantines but it was mostly the Venetians who gave it its present form. In fact, its external walls were built in 1504 by the Venetians.
The castle is ruined today and only a few buildings survive. It was not only the time and wars that caused its damages. This castle also suffered a lot from the earthquake that hit Kefalonia in 1953. At the time of its glory, inside the Castle, there were residences, public buildings, storehouses with food and guns, churches, hospitals, prisons, cisterns of water and generally an organised town. In fact, this Castle was the capital of Kefalonia before Argostoli was made the new capital in 1757. Close to a small square near the castle, you will also see the ruins of the Catholic Church of Saint Nicholas
