Megalithic structure in Moanmore East

In a relatively low-lying area surrounded by hillocks; formerly part of the demesne of Masonbrook House whose outbuildings lay adjacent to the SE. Described in 1837 by Lewis as the 'vestiges of a circular intrenchment within which are the remains of an ancient cromlech' (de Valera and Ó Nualláin 1972, xiv). No visible surface trace of the 'intrenchment' survives but the 'cromlech' is probably represented by a jumble of five limestone slabs (L/W 2m; H 0.5m) none of which seem to be in-situ. These could represent the remains of a collapsed chamber aligned roughly E-W. Faint traces of a possible mound are visible around the slabs and a carved stone trough lies beside it. Possibly a folly associated with the nearby mansion (ibid.)
