Megalithic structure in Ballinascorney Upper

Situated to SE of the summit of Seahan Mountain from which there are extensive views of the Liffey valley, and the passage tombs at Mountpelier. A megalithic structure is located SE of the main cairn (DU024:047001-) which crowns the summit. It is largely peat-covered and comprises a square chamber (1.2m by 1.2m) with some traces of kerbstones to the NW (Redmond and Mac Aonghusa 1994, 36).
