Jeannette Ratcliffe in 'Scilly's Archaeological Heritage' (Twelveheads Press, 1995) gives the following information "On the summit of this hill, built against an outcrop, is a flat-topped cairn surrounded by ten kerbstones housing a rectangular chamber, whose walls protrude just above ground level. No capstones survive. To the south, an oval area enclosed by a low stone and earth wall is either a ring cairn or round house, with a possible entrance on its south side. At the hill's south-western end, a cairn, defined by a kerb of massive slabs (now mostly fallen) and natural rocks, contains a chamber, with slab and coursed walling, partly destroyed on the south-east side. These are two displaced capstones."
