The structure is small, just 2.4 metres in diameter, its wall surviving to a height of roughly 0.4 metres and a thickness of 0.6 metres, with rubble scattered along both the inside and outside of the perimeter. It is barely there, and yet it is clearly deliberate.

This is a hut site, a term used in Irish archaeology to describe the remains of a simple, usually circular dwelling or shelter, most often from the early medieval period, though such structures can span a wide range of dates. What makes the Lackavane example quietly interesting is that it does not stand alone. A second hut site lies approximately 3 metres to the south-east, and a third sits about 26 metres to the north-west. The proximity of these three structures suggests that whatever activity took place here, it was not the work of a single isolated occupant. Whether they were used simultaneously, or accumulated over generations of seasonal use, the bog has preserved their outlines in a way that drier ground rarely allows, holding the stones more or less in place as the surrounding landscape changed around them.
