12 x16 Inches $225 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 (table). 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. There are many beautiful examples of Dolmens in Ireland, and that's another reason to go there I hope you enjoy and thank you for stopping by, Conor dolmen art grave art standing stones art tomb posters
