It is not much to look at now, but the oval earthwork here, measuring roughly 33 metres north to south and 26.5 metres east to west, is the remnant of a rath, the most common form of enclosed settlement in early medieval Ireland. Raths were typically circular or oval enclosures bounded by an earthen bank and outer ditch, built to protect a farmstead and its inhabitants, livestock included, from opportunistic raiding rather than organised warfare. This one has endured in only partial form.

What remains of the enclosing element is uneven. A bank survives along two arcs, running from the north-west around to the north-east and again from the south-south-east to the south-south-west, but along the rest of the circuit the ground simply drops away in a natural-looking scarp, which now performs the work the bank once did. A gap about four and a half metres wide on the southern side may be the original entrance, the point through which people and animals would have passed daily. Immediately outside the enclosure to the south-east, a small quarry has been cut into the ground at some point, likely exploiting the same ridge that made this a sensible place to build in the first instance.
