Drumnasillagh Inland Promontory Fort

An almost semicircular area defined on its NE edge by a cliff face, running NW-SE, and elsewhere by 3 curving collapsed stone wall. A distance of 100m of cliff edge, which is irregular and steep but not sheer, is enclosed. The radius of the semicircle is 50m. The wall is evident in places as a low rise or as a spread of collapsed stone. At its SE end, where it has been mostly robbed to build a nearby field wall, the wall turns to run along the cliff edge for a short distance. The interior is uneven and covered with peat. The site is located strategically on a prominent hill overlooking the valley of the Owenea river to the S. It has a good view of a vast plain to the W but is overlooked by higher ground to the E. The terrain consists of rough bog-covered grazing land. 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.'
