In the Kotsifou Gorge there are 2 old water mill ruins, just a short walk north from Plakias. The second one is the one that is well known because there is quite a bit left of it. It is situated at the small river, over an old stone bridge in lush green surroundings. If you walk upstream from here you will see a new building that was build like the old water mills.
The mills used water to make the blades turn in order to grind wheat and were in use till the mid-1960's, according to the local people.
If you want to go have a look use the directions of walk 2.
