The Venetian Castle of Saint George in Kefalonia is located 7 km southeast of Argostoli, above the village Peratata. 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 1956. 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 organized town. In fact, this Castle was the capital of Kefalonia before Argostoli was made the new capital in 1757. Close to a small square in the castle, you will also see the ruins of the Catholic Church of Saint Nicholas.
References:The Château Royal de Collioure is a massive French royal castle in the town of Collioure, a few kilometers north of the Spanish border. The Château is the juxtaposition of at least four castles. Roussillon was conquered by the Romans around 120 BC and then occupied by the Visigoths from 418. The first mention is about a fortified site in Collioure under siege in 673, by Wamba, king of the Visigoths who lay siege to the “Castellum Caucolibéri” to subdue a rebellion.
In the 12th century, Girard II, the last independent count of the Roussillon, bequeathed his land to Alfons II, King of Aragon and Count of Barcelona. Concerned about the prosperity of Collioure, the kings of Aragon granted privileges and tax exemptions. An annual fair was established, and important works were undertaken in the castle, the port and the town.
