A cashel, which is a ringfort built from drystone walling rather than earthen banks, occupies the northern end of a natural promontory, its roughly circular enclosure measuring about 23 metres across. What makes this particular example quietly interesting is not the cashel itself, common enough across the Irish landscape, but what someone built inside it at a later date: a three-roomed stone house whose southern wall is simply the old curving cashel wall, pressed into domestic service centuries after the enclosure was first raised.

The cashel sits in rocky, undulating pasture on a slight south-facing slope, and the builder of that later house made thoughtful use of the topography. The ancient wall, still standing to an internal height of around half a metre and over a metre on the outside, provided ready-made shelter and a solid foundation for the southern boundary of the dwelling. A lower east-west wall, surviving to about 0.4 metres, completed the northern edge. The western side of the cashel benefits from a steep natural drop of roughly ten metres, meaning the enclosure was, from the outset, positioned to make the most of what the land already offered. The interior of the cashel is itself uneven, sloping gently downward toward the south, so that the house occupies ground that had probably always been the most sheltered and practical part of the enclosure.
