 A trapezoidal cairn of rubble – the upper part of the cromlech and its earth covering now removed – about long by (at its widest), is revetted by a low dry-stone wall.A bell-shaped, south-facing forecourt, formed by the wall, leads to a central passageway lined with limestone slabs set on end.Human remains had been placed in the two pairs of stone chambers that lead from the passageway.
