Wedge tombs are a type of megalithic burial chamber characteristic of the later Neolithic and early Bronze Age in Ireland, typically tapering in width from one end, with a roofing capstone over a long stone-lined gallery. This one is poorly preserved: its chamber, aligned roughly south-south-west, measures at least 4.6 metres in length and about 1.9 metres wide at its western end. The north side is formed by two overlapping slabs, one of which still rises to an estimated height of 1.3 metres. A broken capstone partially covers the inner sidestone, and a small stone near the western end is thought to have functioned as a door stone, a feature seen at other wedge tombs across the Burren.

What gives this particular tomb its broader significance is the landscape it belongs to. Roughan Hill, straddling the townlands of Parknabinnia and Leana, holds what researchers have identified as the densest concentration of wedge tombs anywhere in Ireland. Excavations carried out at three tombs within this group have confirmed that the monuments date to the Chalcolithic and Early Bronze Age, a broad period spanning roughly the late third and early second millennia BC. The Chalcolithic, sometimes called the Copper Age, marks the transitional phase between the Stone Age and the Bronze Age, when metal tools first began to appear alongside older stone-working traditions. Close to this tomb, around 100 to 150 metres upslope to the east, there is a cashel, a type of stone-walled enclosure used for settlement or livestock, and a separate field enclosure that excavation has shown to be of Beaker and Early Bronze Age date. The Beaker period takes its name from a distinctive style of pottery associated with communities across Atlantic Europe during the late third millennium BC. The co-occurrence of tombs and settlement enclosures of broadly the same date suggests that Roughan Hill was not merely a place of burial but an actively managed, inhabited landscape across several generations.
