What reads from a distance as a gentle swelling in the ground resolves, on closer inspection, into a deliberately shaped enclosure: a roughly circular platform, approximately 27 metres north to south and 24 metres east to west, ringed by a scarped bank and a surrounding fosse. The interior sits level and calm under grass, while the external face of the bank drops nearly two metres, giving the structure a presence that only becomes apparent once you are standing beside it.

This is a rath, the most common type of ringfort found across Ireland, and one of thousands that were built predominantly during the early medieval period, roughly between the fifth and twelfth centuries. Ringforts served as enclosed farmsteads, the bank and fosse, which is a ditch dug around the exterior, providing a degree of security for livestock and household alike rather than any serious military defence. The Pallas example sits on a south-west-facing slope, an orientation that would have made practical sense for shelter and light. The fosse here is recorded at 0.85 metres deep and 1.4 metres wide, modest but intact enough to read clearly in the landscape. The site was surveyed and compiled by Denis Power, with notes uploaded in August 2011.

The interior is accessible via a ramp, roughly 4.4 metres wide, constructed on the north-west side of the enclosure. This is a relatively recent addition to the site, suggesting some deliberate management or maintenance effort in the years before the survey. The surrounding land is in pasture, so the approach is likely to involve ordinary farmland, and the usual courtesies around gates, animals, and landowner permission apply. The scarped inner lip is only about 15 centimetres high, but the external face of the bank, standing at around 1.8 metres, gives a clearer sense of the original effort involved in raising this kind of structure. Looking from the interior outward, the slight elevation of the slope and the fall of the bank combine to make the enclosure feel more considered, and more deliberate, than the quiet field it has become.
