Megalithic tomb - unclassified

The National Monuments Service's description

This feature is named 'Dermot and Grania's Bed' on the OS 6-inch map of 1847-52. It is 1.4km SW of Gortahork on level ground above the valleys of the Owentilly River to the W and the Glenna River to the E, both of which reach the sea at the inner end of Ballyness Bay, 1.3km to the N.
Thomas Fagan (1845-8) described it as 'the ruins of an ancient sepulture called Dermot and Grania's Bed which at present consist in one grave 8 feet [c. 2 m] long enclosed at either side by a slab of nearly equal length placed edgeways in the ground and standing 11/2 feet [c. 0.45m] above the latter and supporting as cover to the grave a large flag 6 feet [c. 1.8m] long, 41/2 feet [c. 1.4m] broad and 9 inches [c. 0.2m] thick and a portion of its upper side partially studded with holes 1 to 2 inches [c. 25-50mm] diameter and 1/2 inch [c. 12mm] deep. Here stood other graves the enclosing stones of which have been long since removed to modern erections.'
Two opposed stones, aligned N-S and standing 0.7m apart, mark the site. They are at right angles to a field wall that has been built over them and largely obscures them. The eastern stone is 1m long, 0.1m thick and 0.7m high. The western is 0.9m long, 0.15m thick and also 0.7m high. Just 0.4m W of this is a partly buried, prostrate slab measuring at least 1.3m in maximum dimension. According to local information, there was further structure here until recent decades, but its extent and relationship to the two set stones are unclear. The remains cannot now be reconciled with Fagan's account, and the nature of the site remains to be satisfactorily determined.
