At Aughacliffe stand the remains of a portal tomb, where ancient stones are stacked upon each other in a precarious balancing act. It is located in a hollow, as are most of the dolmens found in Ireland.
The Aughacliffe tomb has two capstones, an unusual feature for dolmens of this type. Only a few others that are similar exist, and they are located in Waterford, Kilkenny, and Down Counties.
