The round cairn, the first of two cairns, is made up of an entrance passage 6m long (which has to be crawled through) and a round chamber that is approximately 18m wide. The long cairn (60m long and 20m wide) resembles a long horn and encompasses two older cairns in the shape of a beehive. The main room (same method of access as above) is divided into three parts separated by large stone slabs. The chamber cairns in the region date back to the Neolithic age (4000-1800 BCE).
