A ringfort, or rath, was typically the enclosed farmstead of a single family, defended not by stone walls but by one or more earthen banks with a fosse, a ditch, cut between them. What makes this one worth a second look is the degree to which its defensive circuit survives as a legible piece of landscape engineering rather than a vague bump in a field.

The enclosure is oval, measuring roughly 40 metres north to south and 35 metres east to west. Two earthen banks define the perimeter, separated by an intervening fosse. The inner bank stands only around 0.4 metres high along its south-south-east to north-east arc, but elsewhere it presents as a scarp of approximately 2.5 metres, a considerable drop that would have made uninvited entry considerably less casual. The outer bank is more substantial along the south-east to north-north-east stretch, reaching 1.6 metres, though it narrows as it continues around the north-north-east to south-east section. A ledge runs along the inner face of the inner bank from south-south-west to north. The outer fosse, the outermost defensive ditch, is no longer sharply cut but can still be read as a gentle slope descending to the base of the outer bank, its edges softened by centuries of agriculture and weathering.
