This fabulous portal tomb, which is also known as the "Glendruid Dolmen", is located
in a small steep sided valley, surrounded by a wooded copse, 20m north of a head water
of the Loughlinstown River and is marked on the OSI map as "Dolmen" and on the
historic map as "Cromlech". The giant capstone which is over 5m in length, 4m in
width, 1.5m in depth and an estimated weight of 40 metric tons, rests on two portal
stones approx; 1.5m in height and two large side slabs. The entrance of the tomb, with
an intact door stone, unusually faces west. Unusual because most portal tombs are
orientated to an easterly direction. The rear of the capstone has a curious V - shaped
groove that stretches right across the upper surface and the peculiarly small chamber is
0.7m below the surrounding ground level. There is some evidence of a cairn or mound
at the rear of the tomb near the back-stone but the majority of it seems to have been
eroded away. Traces of iron ore can be seen running down the face of the granite
capstone.
