The whole burial chamber was once covered by a mound of earth or stones and once these were removed stones were used to block the holes in the sides of the tomb so that it could be used as a shelter for sheep.
The site was excavated in 1968 which revealed four additional stone-holes, one having supported a further chamber stone, the others indicating a possible passage leading off to the northwest. Slight traces of a covering cairn were found to the south and it was shown that the monument had been raised over a pit 0.8 metres deep, filled with clay and stones. Finds included a small quantity of burnt bone, pottery, and flints.
