The monument at Meenformal has been gradually enveloped by peat over the millennia, and whilst much of its structure remains hidden beneath the bog, what’s visible reveals a sophisticated prehistoric burial chamber dating back thousands of years.

The tomb consists of a wedge-shaped gallery, oriented southwest to northeast, measuring 4.4 metres in length. It narrows from 1.6 metres wide at its western entrance to approximately one metre at the lower, eastern end; a characteristic feature of wedge tombs that creates their distinctive tapered shape. The gallery appears to have been divided into two sections: a small portico or antechamber about 1.5 metres long, separated from the main chamber by a jamb-like stone that projects inward from the northern wall. Five roofstones, some partially dislodged over time, still lie across the gallery, their longer axes spanning the width of the chamber. These substantial slabs, averaging 1.5 metres in length and at least 15 centimetres thick, would have originally rested directly on the gallery sides to create an enclosed burial space.

The monument retains evidence of its original architectural complexity, including outer walling that stands about half a metre beyond both sides of the gallery and a facade stone at the northwest corner that rises 0.9 metres high. An oval mound, now overgrown with bog vegetation, surrounds the entire structure, measuring 9.5 metres from northeast to southwest and 6.5 metres from northwest to southeast. Unfortunately, a later field wall crosses both the southern side of the gallery and the southwestern end of the structure, obscuring some of the original features. Despite this intrusion and the encroaching bog, the tomb remains a remarkable example of Ireland’s Neolithic engineering, where ancient communities invested considerable effort in creating lasting monuments for their dead.
