The outline is modest, roughly four and a half metres east to west and four metres north to south, and the stones that mark it rise only twenty to thirty centimetres above the ground. Easy to walk past, easy to dismiss as fieldstone debris, it is in fact a probable hut site, the remnant of a structure built within the protection of a cashel.

A cashel is a roughly circular stone enclosure, a form of early medieval settlement found widely across Ireland, particularly in the west. The enclosure at Poulacapple provided the boundary wall within which daily life was organised, and this hut site sits approximately at its centre. The subcircular shape of the structure is typical of early medieval building practice in Ireland, where rounded or oval ground plans were common before rectangular forms became dominant. A second hut site lies just to the north of this one, suggesting the cashel once sheltered at least a small community or household group, with separate structures arranged within the same defended space. The stones that survive today are low and largely buried under moss, which is itself a measure of their age and the degree to which the site has merged back into the landscape over centuries.
