The visible monument comprised two periods of construction. First, a small megalithic chamber, characterized by a pair of projecting portal-stones flanking a high closing slab, had been built, and surrounded by a small oval cairn. The chamber had been rifled, but a pit in front of the portal, and sealed beneath the cairn, contained portions of several Neolithic pottery vessels of a fine, undecorated, ware. The second structure consisted of a large megalithic burial chamber built to the east of the first monument. The cairn of this, eastern, chamber was roughly rectangular in plan, and extended westward so as to incorporate the whole of the earlier monument. Pottery from the eastern chamber, and its forecourt, represented several Neolithic, and Bronze Age, wares. The elaborate system of blocking in this forecourt was found virtually intact.
