Lake Doxa is an artificial lake at an altitude of 900 meters, located in Ancient Feneos of Corinthia. Its construction was completed in the late 1990s, and was based on the torrent of Doxa flowing in that area. In the past, the lake has been flooded several times covering the entire Feneos plain and destroying the crops of the inhabitants of the area.

In the center of the lake there is the chapel of Saint Fanourios. Previously there was the Monastery of St. George, but due to the floods it was moved in a short distance from its original position, next to a hill.
