This portal tomb is at the north end of a long cairn, once much larger than is now visible, originally extending south downhill for 80–90ft (24.5–27.5m). The gigantic granite capstone is estimated to weigh some 35 tons and it may have been an erratic boulder already on the site, undermined and propped up with portal and side stones to form this spectacular dolmen. Excavation early in the 20th century discovered bone and pottery.
