Summary

Near Maghery village, inland promontory fort with a total site foot print of approximately 0.4ha is positioned on an irregularly shaped neck of land projecting S from the N shore of Aghnish Lough. This promontory is defined on the E, S and W by the lake and at the N by a stone wall. Univallate with two possible original entrance features. Both gaps are placed centrally and consist of simple narrow breaks in the enclosing feature. No evidence for any internal features on the surface. Rampart survives well throughout its length but has been partially altered by a modern wall positioned at its crest. Interior under scrub and overgrowth with rock outcrop at edge of land. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey maps. Site survey by Lacey in 1983.

Entrances

Original entrance feature is positioned at centre of enclosing element. It comprises a simple 1.1m gap. A second entrance feature is again placed centrally and is defined by a 1.1m wide gap with two large slabs forming the wall terminals to either side (Lacey 1983).

Enclosing Works

Irregular shaped area defined by Aghnish Lough at E, S and W. A narrow neck of land at the N is cut off from the mainland by a stone wall that runs from rock outcrop at the edge of the neck. This wall comprises large stones with flat edge outside and is surmounted by what is likely to be a modern wall (Lacey 1983).
