Eighteenth- and nineteenth-century antiquarians had a habit of attributing any ancient stone structure to druids, and this megalithic tomb on the northern shore of Cleggan Bay in Connemara is no exception. The label has stuck, even though the monument long predates any druidic tradition and belongs instead to the Neolithic period, when communities along Ireland's Atlantic fringe were constructing elaborate stone galleries as places of communal burial.

What survives is a gallery tomb aligned roughly east-south-east to west-north-west, and its layout repays careful attention. The eastern, front portion is incomplete, and scholars have debated how to read the arrangement of upright stones, or orthostats, in this section: they could represent the sidestones of a chamber, or they might have defined a narrow asymmetrical court, a shallow forecourt-like space sometimes found at the entrance to gallery tombs. West of a pair of jambs set transversely across the gallery, the tomb divides into two chambers, separated by a septal stone, a slab set across the passage to partition the interior. The innermost western chamber is noticeably narrower and built with lighter stonework than the rest, suggesting either a change in construction phase or a difference in intended function. A substantial roofstone still covers the eastern of these two chambers, and a long displaced stone lying just west of the jambs is likely a lintel that has shifted from its original position. Traces of the covering mound remain on the south side of the structure. The tomb was described and documented in detail by Ruaidhrí de Valera and Seán Ó Nualláin in their 1972 survey of megalithic tombs in County Galway and beyond.
