Lough Aghnish Promontory Fort

A promontory on the N shore of Aghnish Lough is cut off by a stone wall which runs from the rock outcrop on the W to within 5m of the E side. The top of the wall is comprised of small stones and is probably modern rebuilding but the base, c. 1m thick, is composed of larger stones with their flat edges to the outside. Two slabs 1.1m in length in a central position and at right angles to the wall would appear to be the remains of an entrance. Other slabs on the inside N of the wall continue the line of the entrance. The original gap of 1.11m is now filled by modern building. The above description was derived from the 'Archaeological Survey of County Donegal. A description of the field antiquities of the County from the Mesolithic Period to the 17th century.'
