It is a wedge tomb, the most numerous type of megalithic monument in Ireland, built during the late Neolithic and early Bronze Age periods, typically between around 2500 and 2000 BC. The defining feature of the type is a tapered stone gallery, wider and taller at the western end, which tends to face the setting sun. This example follows that pattern closely, its interior narrowing from 1.2 metres at the western entrance down to 0.95 metres at the eastern end, with the roof line dropping in the same direction.

The gallery, just over three metres long and aligned roughly east-north-east to west-south-west, is built from two stones on each side. The western pair are shorter and set slightly inward from the outer two, creating a subtle layering to the structure. A backstone closes the eastern end. Two roofstones cap the whole, and the gallery is enclosed by closely-set outer walling, a construction detail that would originally have helped support the roof and retain any covering mound. Unusually, there are no surviving indications of such a mound here, though whether it was never built, or simply eroded away over the millennia, is difficult to say. The tomb was recorded in detail by Ruaidhrí de Valera and Seán Ó Nualláin in their Survey of the Megalithic Tombs of Ireland, published in 1982, which remains a foundational catalogue of these monuments across Cork, Kerry, Limerick, and Tipperary.

The valley setting is worth noting for what it tells us about how these structures were placed in the landscape. Rather than commanding a hilltop, this tomb occupies a sheltered position below the ridge, tucked into the topography in a way that feels deliberate. The roofstones and outer walling survive, which is more than can be said for many comparable monuments, making this a relatively complete example of a monument type that was once widespread across the Irish uplands.
