Pretty beach in Sardinia. It's on this board because according to my dad's autosomal dna test, his closest genetic relatives live in Sardinia...he must have gotten a big dose of dna from his mother through whom we have our only Italian ancestor!
A dolmen, also known as a portal tomb, portal grave, or quoit, is a type of single-chamber megalithic tomb, usually consisting of three or more upright stones supporting a large flat horizontal capstone. Most date from the early Neolithic period (4000 to 3000 BC). Dolmens were usually covered with earth or smaller stones to form a barrow, though in many cases that covering has weathered away, leaving only the stone "skeleton" of the burial mound intact.
