Gardiki Castle is a Byzantine castle from the 13th century, located on the southwestern coast of Corfu, near the village of Agios Matheos, about 25km from Corfu Town. It is the only surviving medieval fortress in the southern part of the island. The strategic position of Gardiki provided protection for the fields and southern plains of the island.

It was one of three castles that defended the island before the Venetian era, along with the castle of Kassiopi in the northeast and Angelokastro in the northwest. The three castles formed a defensive triangle. The castle sits on a hill and has an octagonal shape with eight towers and three gates. Although in poor condition, the towers still retain their full height. Click here to view the location on Google Maps.

There is no designated parking area near the castle, but as it is not a crowded tourist destination, roadside parking is usually available. Gardiki Castle is free to visit, though there is no informational signage or explanation about its history.

Grava of Gardiki

Grava of Gardiki is a 20 meters long horizontal cave 900 meters from the Byzantine fortress of Gardiki. Excavations have uncovered tools made of flint and animal bones, now exhibited in the Archaeological Museum of Corfu. These findings date back to the Upper Paleolithic Period, making the site the oldest known human settlement on the island. During that time, Corfu was still geologically connected to mainland Greece.

The trail leading to the cave begins with a signpost but continues through an olive grove. While the cave itself does not offer much to see, it has a panoramic view of the southern part of Corfu. Click here to view the location on Google Maps.
