Aghaglassan Stone Ringfort

Internal diam. c. 21.5m. A subcircular area defined by a low bank composed of stones with some earth. The wall no longer survives to the NW and N, and the E side has been obliterated by the road, which is co-tangent to it. There is a possible entrance in the SW quadrant. It is situated on an uncultivated plateau used for pasture, over-looking the N, with higher ground to the S. 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.' Compiled by: Brian Lacey with Eamon Cody, Claire Cotter, Judy Cuppage, Noel Dunne, Vincent Hurley, Celie O'Rahilly, Paul Walsh and Seán Ó Nualláin (Lifford: Donegal County Council, 1983). In certain instances the entries have been revised and updated. Date of upload: 22 September 2008
