This is a bowl-barrow, a type of funerary monument typically consisting of a rounded earthen mound covering a burial, so named for its shallow, bowl-like profile when viewed in cross-section. What makes this particular example quietly notable is its modest but precise geometry: six metres in diameter, 1.25 metres high, with a small flattened area at its summit inclined slightly to the south.

Recorded by Timoney in 1984, the mound shows no evidence of a surrounding bank or fosse, the shallow ditch that often encircles such monuments and from which earth was sometimes quarried to build the mound itself. Its absence here gives the barrow an unusually clean, unencumbered form. The site is catalogued in connection with the broader Carrowmore complex, one of the largest concentrations of megalithic monuments in Ireland, and is referenced by Bergh as Carrowmore 11A. Tobernaveen sits within this remarkable landscape on the Cúil Irra peninsula, where prehistoric communities left an exceptional density of tombs, cairns, and earthworks across a relatively compact area.
