Measuring just 6.9 metres by 6 metres, it is enclosed by a drystone wall, built without mortar, averaging about 60 centimetres high and over a metre wide. That wall-to-interior ratio is itself a curiosity: the boundary is almost as substantial as the space it defines. The internal corners are slightly rounded rather than sharply angled, and on the western side an ill-defined entrance is marked by a notched slab resting on the wall's surface, a deliberate detail in an otherwise modest structure.

Inside the enclosure, and lending the whole thing its peculiar atmosphere, is a low rectangular mound of stone, only about 40 centimetres high, with traces of coursing, meaning stones laid in deliberate horizontal layers, visible at its edges and running into the body of the mound itself. Notably, the mound contains a significant amount of quartz. The use of quartz is not unusual in Irish prehistoric and early medieval contexts; the stone appears repeatedly at burial monuments and ritual sites across the country, from the quartz facade of Newgrange to smaller field monuments scattered throughout Kerry, suggesting an association with light, significance, or ceremony that we can no longer fully read. Whether the mound here served a ritual purpose, marked a grave, or formed part of some other structure entirely, the stonework shows enough care and intention to rule out the merely practical.
