Fort, Liscumasky, Co. Monaghan

Drumlins, those elongated egg-shaped hills shaped by retreating glaciers, were favoured sites for early Irish ringforts precisely because elevation and visibility came ready-made. The fort at Liscumasky takes advantage of exactly this, sitting at the end of an east-west ridge in a way that would have commanded clear sightlines across the surrounding countryside.

The monument itself is a roughly circular enclosure, approximately thirty metres across at its widest, defined by a grass-covered earthen bank with a fosse, or defensive ditch, running around much of its outer edge. A ringfort of this kind, sometimes called a rath, was typically a farmstead enclosure built during the early medieval period, roughly between the fifth and twelfth centuries, and the layered defences here follow that familiar pattern: an inner bank, an outer ditch, and traces of a further external bank beyond that. The original entrance, about three metres wide, faces east, which was a common orientation in Irish ringfort construction. Inside the western arc of the bank, a depression roughly nine metres long and half a metre deep breaches the bank at the north-northwest, possibly the result of later disturbance or gradual collapse. By the time survey work was carried out in 2000, the site had become considerably more overgrown than it appeared in earlier records dating from 1968, adding a layer of obscurity to features that were already subtle at ground level.
