A menhir (French, from Middle Breton: maen, "stone" and hir, "long"), standing stone, orthostat, lith or masseba/matseva is a large upright standing stone. Menhirs may be found singly as monoliths, or as part of a group of similar stones.
Practically nothing is known of the social organization or religious beliefs of the people who erected the menhirs. There is not even any trace of these people's language; however we do know that they buried their dead and had the skills to grow cereal, farm and make pottery, stone tools and jewelry. Identifying their uses remains speculation. It is likely that many uses involved fertility rites and seasonal cycles. Many menhirs are engraved with megalithic art.
