Description : Massive cairn 12m high x 80m diameter built mostly of stone. Explored 1886-87 by mining down from the centre. No finds of interest. Reportedly used as a beacon site in the 17th century.
Illicit stone removal on lower, south-west slope of cairn has exposed up to 2m of a possible revetement composed of coursed, thin limestone (Brassil, K 1986b, 33).
Largest cairn in Wales, 330ft NW-SE x 223ft NE-SW x 40ft high. Composed of local limestone. Summit has been lowered or flattened. Excavated by Boyd Dawkins 1886 and 1887 by sinking a shaft in the centre to a depth of 26ft at original ground level. From base of shaft a drift was made 6ft high and 4ft wide in a NW direction for distance of 30ft. Two other drifts intersected the first. No chamber revealed and no finds recovered (Davies 1949, 156-62).
Situated on summit of Gop Hill. The stabilisation work carried out fairly recently by Clwyd CC (?Andre Berry) seems to have been unsuccessful (CPAT 1999).
It is possible that it covers a middle Neolithic Passage Grave.... The dominant siting and scale of the monument suggest comparison with the great cruciform Passage Graves of Ireland and the presence of decorated orthostats from such a tomb in Liverpool make it geographically feasible (Lynch, Frances, 2003).
