Pentre Ifan Dolmen is a prehistoric monument consisting of seven principal stones. The largest is the huge capstone, 5 m (16 ft) long, 2.4 m (7.9 ft) wide and 0.9 m (3.0 ft) thick. It is estimated to weigh 16 tonnes and rests on the tips of three other stones, some 2.5 m (8.2 ft) off the ground. There are six upright stones, three of which support the capstone. Of the remaining three, two portal stones form an entrance and the third, at an angle, appears to block the doorway.
