An ancient stone monument, probably a Druids Altar, is prominently located 400 yards south of the lake in a sloping pasture anciently named , meaning field of the Scur. Set against the spectacular backdrop of Lough Scur and Slieve Anierin, it is marked Dermot and Grania's Bed on some maps. Although two erect stones at the south have certainly been artificially set upright, this anomalous monument is extremely doubtful and, on the evidence, cannot be accepted as a megalithic tomb, but rather an attempt to split a rock outcrop from underlying bedrock. It may have been a Druids altar before Christianity. There is also a Cist located here.
