Dolmen de la Fontaine au Son

The Dolmen de la Fontaine au Son is a Neolithic tomb built from sandstone slabs in the Vienne department of western France. This site actually contains two separate structures: one retains its original form while the other shows signs of deterioration with scattered blocks.

These tombs were built around 5000 years ago during the Neolithic period, when people in this region constructed shared burial sites from local stone. The structures received official recognition as historical monuments in 1955, ensuring their protection.

The name references an ancient spring that once flowed through this area, connecting the stone structures to the landscape's water sources. Locals have always recognized how water shaped settlement patterns around these megalithic tombs.

The site is open and accessible at any time without fees, located in a rural setting. Wear sturdy shoes since the ground can be uneven and vegetation may partially cover some areas of the stones.

The main structure features a distinctive portico facing northeast, supported by three massive vertical stones that form its entrance frame. The roof consists of two separate slabs that were carefully balanced on these supports, showing sophisticated building knowledge for the era.
