The rectangular foundations, measuring roughly six metres by one and a half metres internally, are thought to have served either as a house or an animal-pen, though their precise original purpose remains uncertain. The drystone walls, built without mortar in the traditional manner, have largely collapsed, standing now to no more than 83 centimetres at their highest point, with a thickness of nearly one and a half metres suggesting a solidity that outlasted whatever roof they once supported.

The building is one of several features within the burial ground at Cill Fhaoláin, known in anglicised form as Killelane. Alongside the foundations, the site contains grave mounds, cross-slabs, and a leacht, which is a low cairn-like structure associated with early Christian devotion and commemoration. There are also traces of what may be an earlier circular enclosure beneath or around the current rectangular layout, hinting at a sequence of use that predates the more formal arrangement visible today. The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a landmark study of one of Ireland's most archaeologically dense regions. The rectangular structure abuts the southern side of a dividing wall, and a second defined area to its south is outlined by a low bank, suggesting the space was organised with some deliberate intention, even if its domestic or agricultural function was secondary to the sacred character of the broader enclosure.
