The rath, as this type of enclosure is properly called, is a ringfort of early medieval date, the kind of enclosed farmstead that once dotted the Irish countryside in the tens of thousands. Most have been ploughed away or built over. This one survives, sitting on a low gravel ridge along a valley floor, with open grassland rolling away in every direction and long, clear sightlines to all points of the compass.

The enclosure is roughly oval, measuring approximately 48 metres east to west and 39 metres north to south. Around most of its circuit, what remains is a single low, wide bank about two metres across. But on the northern and north-western arc, something more survives: traces of an internal bank, with a fosse between the two. A fosse is simply a ditch, in this case around five metres wide and nearly two metres deep where it is preserved, separating an inner and outer earthen wall. This kind of double-bank arrangement would have made the enclosure considerably more formidable than the surviving outer circuit alone suggests. It is thought that the southern half of this inner defensive system has been levelled over time, leaving the site looking simpler than it once was. The entrance gap on the eastern side, five to six metres wide, is probably wider now than it was originally, the edges having spread or been deliberately opened at some point.
