It is a sweathouse, a type of early Irish sauna used for therapeutic purposes, and it sits quietly absorbed into the landscape at the edge of Kinard West, where the townland meets Tobarnamoodane.

The structure is drystone, meaning it was built without mortar, relying entirely on the careful placement of stone upon stone. Its entrance faces north and is modest to say the least, standing roughly 0.9 metres high and 0.6 metres wide, with a flat lintel spanning the opening. Inside, the chamber is D-shaped, its roof formed by corbelling, a technique in which stones are layered so that each course projects slightly inward over the one below until the gap closes. The floor is cobbled, and the whole thing is capped with flags. Sweathouses of this kind were typically used by heating the interior with a turf fire, clearing out the embers, and then crawling inside to sweat in the residual warmth, sometimes emerging to plunge into cold water nearby. The presence of a stream roughly thirty metres to the east fits that pattern precisely. The structure is marked on the 25-inch Ordnance Survey map and sits close to what would have been settled land, which is consistent with sweathouses generally: they were communal and practical, not remote or ceremonial.
