Black Pigs Dyke Ancient Ulster Fortification Cavan/Monaghan/Fermanagh Border

The "Black Pig's Dyke" (Irish: Gleann na muice duibhe - literally, "glen of the black pig") is a series of discontinuous defensive earthworks built along the southern boundary of the old Irish province of Ulster. Today remnants of the banks and ditches stretch through South County Down, County Armagh, County Monaghan, County Cavan, County Leitrim and South County Donegal. It is assumed that The Black Pig's Dyke was built for the protection of Ulster from tribes to the south in Connacht and Leinster, whether the threat was of invasion or cattle raiding. A stretch in Co. Monaghan has been excavated. This revealed that the original construction was of a substantial timber palisade with external ditch. Behind the palisade was a double bank with intervening ditch. The timber structure was radiocarbon dated to 390-370 BC, so the whole of Black Pig's Dyke may date to that period.
