This monument lies at the bottom of an inhospitable, boggy valley on the island of Hoy, halfway along the glen to Rackwick Bay. The tomb was laboriously carved out of a block of red sandstone 8.6 metres long, between 4.4 and 3.9 metres across and at least 2 metres high. It lies roughly north-south and is tilted so that its north end is partly buried. The interior consists of a very short passage leading to two side cells with low sills—essentially a Bookan-type tomb. The entrance faces west and measures 0.85 x 0.75 metres. The entrance passage is a short one, less than one metre long and really only indicated by a change in elevation of the roof, which becomes higher at this point. Both cells have curving walls, the southern one is somewhat larger (1.5 x 0.9 x 0.8 metres) and has a small ledge at the back end.

Originally, the tomb was sealed by a large blocking stone, which now lies in front of the entrance but apparently was still in place in the 16th century. Its subsequent removal, which caused a good deal of damage to the entrance, is unrecorded and nothing is known as to what (if anything) was found within.
