Lac de Castillon, Artificial lake in Castellane, France
Lac de Castillon is an artificial lake in the Alpes-de-Haute-Provence region with expansive green waters surrounded by mountains and forested terrain. The lake spans several kilometers and reaches significant depths, making it a substantial body of water in the area.
The construction of the Castillon Dam in 1948 submerged the original village below the water, which then merged administratively with neighboring Castellane. This project was part of wider regional infrastructure development for water management and power generation.
The villages around the lake, such as Saint-Julien-du-Verdon and Saint-André-les-Alpes, display traditional stone architecture with narrow streets typical of Provence. Daily life in these small communities centers on water activities and the surrounding landscape.
Water conditions are best for activity from spring through autumn when weather is more stable and equipment rental is available. The shoreline can be accessed from several nearby villages, though some areas offer better facilities and parking than others.
Few visitors realize that remains of the submerged original village lie beneath the surface and occasionally become visible during clear conditions. This hidden underwater history adds an intriguing layer to what seems like a simple modern recreation area.
