Tumiac tumulus

Tumiac tumulus is a prehistoric mound of earth rising from the Breton landscape with a conical shape that stands out clearly from its surroundings. Inside it holds an ancient burial chamber with standing stones arranged to form an enclosed space.

The mound was built during the Stone Age to serve as a burial place for early inhabitants of the region. Archaeologists working inside found tools and objects that showed how people lived in that distant period.

The site carries a name rooted in Celtic language and has shaped the local landscape for thousands of years. Visitors walking around it can sense how significant such places were for the communities that built them.

The mound is accessible from the outside and can be circled on foot along a path that gives a clear view of its shape. The best time to visit is during good weather when you can see the surroundings and landscape clearly.

The site sits on a coast that holds many such burial mounds, and from its top you can see the sea and surrounding landscape. This location was no accident for the builders but showed how significant this place was for the region.
