We are here in the presence of a large dolmen discovered in 1768 by the villagers. They actually believed they had discovered the remains of a monastery. The stripping of the dolmen delivered leather spatulas, vases, ashes and flint knives. It was estimated in 1894 that this monument contained 150 skeletons. It was excavated in a more scientific way in 1899 by Mr. Mortillet and restored in 1970. The archives show the presence of roofing slabs until the 18th century. The dolmen consists of large sandstone slabs forming the pillars. The gaps between the pillars are filled with flat stones.
