This ancient monument, situated about 650 metres from the coast on the north side of a shallow valley, consists of a partially concealed gallery tomb with its original outer walling still largely intact. The structure, which dates back to Ireland’s Bronze Age, showcases sophisticated construction techniques including corbelling; a method where stones are layered to create a narrowing roof span, and substantial roofstones that once covered the eastern chambers.

The tomb’s gallery stretches 6.3 metres in length, narrowing from 1.25 metres at its entrance to just 0.75 metres at the rear. It’s cleverly divided by a septal stone into two distinct sections: a portico at the front and a main chamber that still retains partial roofing. The main chamber itself runs 4.2 metres long and contains multiple sidestones and a backstone, though much of the detail is obscured by fill material that has accumulated between the outer walls and the gallery sides over the centuries. Two massive roofstones remain in position above the eastern portion of the chamber, whilst a third has slipped southward; this displaced slab, measuring 1.75 metres square and 0.25 metres thick, was noted by antiquarian Thomas Fagan as still being in place when he visited in 1847.

The outer walling demonstrates remarkable preservation, particularly on the northern side where seven stones converge towards the gallery, their heights varying from 1.75 metres down to 0.5 metres. Archaeological assessments conducted in 1999 revealed that the surrounding Kilbarron townland contains multiple prehistoric features, including a nearby enclosure marked as Carrickcullen on historical Ordnance Survey maps. The wedge tomb’s sophisticated construction, with its carefully positioned orthostats, corbelled walls, and substantial roofing slabs, represents the considerable engineering skills of Ireland’s Bronze Age communities and their enduring reverence for commemorating the dead through monumental architecture.
