The Kouramila Megali Grava cave is located on Mount Pantokratoras
in the village of Agios Mattheos. The cave is 8.8 metres long, 6.5 metres wide and 2.7 metres high. The cave was used as a corral.
During the Palaeolithic period the level of the sea was much lower and Corfu was not an island but connected to the mainland of Greece. Separation from Epirus occurred during the Neolithic
period, around 10,000 B.C., when the sea level rose as the ice melted. Inside the Kouramila Megali Grava cave you can see the geological situation of the past.
