It is not immediately obvious what it once was. The mound measures just under fifteen metres across and rises to about one and a half metres, and at its core lies a rectangular chamber some four metres long and three and a half metres wide. This is a clochan, a type of dry-stone beehive hut constructed without mortar, traditionally associated with early medieval monastic and agricultural life in the west of Ireland. The entrance, set in the eastern wall, is still faintly traceable beneath the collapse that has gradually filled and obscured the interior over centuries.

The structure sits within a wider landscape dense with early remains. Dún Eochla itself is a concentric stone fort occupying one of the higher points of the island, and this clochan would originally have functioned in relation to that broader settlement pattern, whether as a dwelling, a storage cell, or part of a monastic enclosure. A second clochan lies approximately thirty metres to the east-south-east, suggesting this was not an isolated building but part of a small cluster. The limestone plateau of Inis Mór, with its thin soils and exposed karst, preserves these structures unusually well in outline even when the fabric has largely fallen in, and the terrace setting here gives the site a particular clarity in the wider topography.

The mound is poorly preserved and heavily choked with collapsed stonework, so there is little to see of the interior chamber without close inspection. The entrance traces on the eastern wall are the most legible surviving feature. Given the proximity to Dún Eochla and the second clochan to the east-south-east, the site reads best as part of a group rather than as a single monument in isolation.
