The Castle of Agios Georgios crowns a hill southeast of Argostoli on Kefalonia, with panoramic views across the countryside and towards the town. The Byzantine-founded stronghold was rebuilt by the Venetians in the early 16th century; its entrance and three successive gates are among the most striking parts of the site. Explore the ruins and take time to look out from the walls. The ground is uneven, and the remains have limited interpretation, so this stop suits visitors interested in the setting and history more than a fully presented museum.
A Venetian stronghold above Argostoli

The castle stands on a hill southeast of Argostoli, about 300 metres above sea level. The site was founded by the Byzantines in the 12th century, but most of the architecture visible today dates to the Venetian rebuilding in the early 16th century. The Venetians regained control after a brief period of Ottoman rule and reshaped the fortification.
Their works included an outer wall 620 metres long, a citadel known as the kastro and a road from Argostoli that wound around the hill, hidden from approaching pirate vessels. The thick walls enclose traces of earlier phases, though the Byzantine sections are difficult to distinguish among the later structures.
The entrance and the views

The entrance is a good place to study the castle’s defensive layout. Three gates follow one another, protected by a large bastion above and beside them. The surviving fortifications and the surrounding landscape make the site rewarding for a slow walk and photography.
From the hilltop, views extend over the countryside towards Argostoli and beyond. The ruins are not extensively interpreted, so visitors hoping for detailed historical displays may find little explanation on site. The setting and the remains themselves provide the main focus.
