2 kilometres northwest of Murroe in County Limerick, and yet it never appeared on Ordnance Survey historic maps. It was only formally identified in 1958, when a member of the Glenstal Archaeological Society named Mr O Riordáin recorded it. That it went uncharted for so long is less surprising once you see the state of it: the large, flat capstones that once roofed the chamber are no longer in place, and three of them lie displaced to the southeast, reducing what was once an enclosed megalithic gallery to something more like an open-sided arrangement of standing stones.

Wedge tombs are a type of megalithic monument built during the late Neolithic and early Bronze Age, typically consisting of a long, narrowing stone gallery, wider and taller at one end, often covered by a cairn of smaller stones. This example, described in detail by the archaeologist Elizabeth Shee Twohig in 1990, has an internal gallery running roughly northeast to southwest, about four metres long. The northern side survives largely intact, defined by four orthostats, the upright slabs that form the walls, while the southern side retains only one at each end. Two further stones protrude just above the cairn material along the northern exterior, suggesting an outer revetment wall once enclosed the whole structure. The capstones, according to local information, were removed in the early 1900s by workers on the Barrington estate of Glenstal Castle, who also apparently dug into the southwestern end of the interior, leaving an excavation roughly a metre below the tops of the remaining orthostats. There is also a quiet puzzle about the entrance. Most wedge tombs open to the west, but here the stone closing the western end is the tallest and thickest in the whole structure. Shee Twohig noted that the eastern stone is considerably thinner and lower, and would have been far easier to shift, suggesting the entrance may have faced east instead. She identified similar arrangements at Baurnadomeeny in County Tipperary and at Lough Gur, also in County Limerick.

The tomb sits at around 183 metres above sea level, so the ground underfoot can be soft and uneven, particularly after wet weather. It lies about 0.75 kilometres northwest of Glenstal Abbey, which provides a useful landmark when approaching from the road near Murroe. There is no formal access path or signage, so progress across the pasture requires some care. The displaced capstones to the southeast are worth examining closely; their size gives a sense of how substantial the original covering must have been, and their position makes it easier to read what was deliberately removed against what simply collapsed or shifted over the millennia.
