The structure is modest by any measure, roughly 5.2 metres east to west and just over 4 metres north to south internally, with walls largely worn down to earthen ridges, though the inner face survives to about 42 centimetres at two of its corners. What makes the hut notable is not its size but its company: it sits within the same enclosure as the remains of an oratory, a bullaun stone (a boulder with one or more rounded depressions, typically associated with early Christian ritual use), and a cross-inscribed ogham stone, ogham being the early medieval Irish script carved as a series of notches along a stone's edge.

The site is known as Kilfountan or Teampall Fionntain, names that recall an early saint, Fionntain, to whom the place was dedicated. The enclosure bank and an internal dividing bank actually serve double duty as the western and northern walls of the hut, suggesting careful reuse of existing boundaries rather than construction from scratch. A quernstone, probably of a type classified as Disc A, was recovered from the site and is now held in the museum in Cork; quernstones were used for grinding grain and their presence is a quiet indicator of domestic or communal life within what might otherwise seem a purely devotional complex. Strikingly, the site continued to function as a burial ground into the nineteenth century, with children still being interred here, a practice recorded in the Ordnance Survey Name Books for the parish of Kildrum. That kind of continuity, stretching from early Christian monasticism through to relatively recent times, gives the place an unusual depth of occupation that its unassuming, low-lying setting does little to advertise.
