August 16, 2025, Dolmen géant de Crucuno

The dolmen stands in the middle of the village, close to a house. It once had a long passage and measured 27 meters in length. The cover plate weighs approximately 40 tons. For a long time, it served as a barn.

Walking through the woods of Erdeven, one can find among the trees a set of megaliths among which is the one called Caesar's Chair. It owes its name to the occupation of the place by Roman troops in Antiquity, even if Caesar never came here.

This dolmen would have long served as a stable. It is made up of nine pillars and the covering slab weighs more than 40 tonnes. Access to the dolmen was formerly via a long corridor of 27 meters which no longer exists.
