What is recorded here

The fairy fort or earthen ringfort in Rathmactiernan is in County Sligo, Ireland. It sits on a narrow ridge about 100 metres northeast of Killoran North Lough and overlooks a church and graveyard 150 metres south. The 1838 Ordnance Survey map showed an embanked circular area, but the site is now levelled. A raised roughly circular area 32.4 metres wide remains, with a scarp reaching 2 metres high along the southeast edge where the ground falls away steeply.

In pasture, on top of a narrow ridge, c. 100m NE of Killoran North Lough and overlooking a church (SL025-112001-) and graveyard (SL025-112002-) c. 150m to S. Indicated on the 1838 OS 6-inch map as an embanked circular area but now levelled. It is evident as a raised roughly circular area (32.4m NW-SE; c. 35m NE-SW) defined by a scarp (H 0.7m) which is highest along the SE arc (H 2m) where the ground falls away steeply to E and S from the perimeter. The SE portion of the interior is raised to compensate for the hillslope. A WNW-ESE field boundary crosses the interior just N of centre. The above description is derived from the published 'Archaeological Inventory of County Sligo' compiled by Ursula Egan, Elizabeth Byrne, Mary Sleeman with Sheila Ronan and Connie Murphy (Dublin Stationery Office, 2005).
