The sink holes of Argostoli are still considered a mystery and are part of a rare geological phenomenon of Kefalonia. Katavothres is located 3km outside Argostoli and it is a must-see attraction because of its natural beauty and a famous club-café situated there.
In 1835, the phenomenon was rare enough that the English built some corn mills and while earthquakes broke the water wheel, amazingly nothing happened to alter this trend of water coming in and going under. One could well ask where the wheel was set up so as to work. They needed flowing water. This is where the rare geological formations came in to play.
At Katavothres the sea flows inland and enters sinkholes on the earth that is below sea level. It is assumed that there are caverns below the seabed which is where the water flows in. The mills used to be run in these holes. The water would flow swiftly through the artificial channels and the wheel would start spinning.
