From Kilkenny Archaeology’s Facebook Page:
Today Kilkenny Archaeology and Shirley Clerkin (Monaghan heritage officer) were carrying out detailed mapping of the linear earthworks of the dyke in south west county Monaghan. This is part of the Black Pig’s Dyke Regional Project which is funded by Monaghan, Roscommon, Leitrim, Cavan and Longford county councils.
