It measures roughly two and a half metres north to south and just over two metres east to west, the dimensions of a space barely large enough to shelter one or two people. The drystone wall, a technique using no mortar, has long since tumbled, leaving a low and discontinuous ring perhaps half a metre tall in places, with loose stones strewn across the interior. What makes this particular site quietly telling is the way the wall was cut into the rising ground at its southern side, a practical response to the slope, and how it abuts a surrounding network of relict field boundaries, the ghostly outlines of an agricultural landscape that was once actively managed and is now largely abandoned.

Hut sites of this kind are found across upland Ireland and are often difficult to date with precision. They may represent seasonal shelters used by people tending animals on higher ground during summer months, a practice known as booleying, or they may be the remains of more permanent small dwellings from any number of periods. What the Tooreennamna site adds to that general picture is the visible relationship between the structure and the surrounding field system, suggesting it was not an isolated feature but part of a broader, organised use of this hillside. A second hut site lies approximately thirty metres to the southeast, reinforcing the impression that this was once a worked and inhabited place rather than a solitary refuge.
