The sinks in Kefalonia are one of the many geological attractions of Kefalonia, located at a distance of about 2 km away from Argostoli, in the cape of Agios Theodoros.
The sinks are cracked – openings in the ground next to the sea. The water which enters from there follows a wide underground path across almost the entire island.
This was revealed in 1963 when geologists Viktor Maurin and Josef Zötl from the Technical University of Graz, dropped 160 pounds of paint into the sinks. Two weeks later, traces of paint were found 14 km away, on the other side of the island, as well as in the Lake Cavern of Melissani.
In early years, the power flow of the water was used to power mills but now they remain unused.
The mills were constructed by the Englishman Stewens, who was the first person to observe this phenomenon.
