The Unstan Cairn is unusual because it is a circular stalled cairn combining different cairn styles. Large slabs of Orkney flagstone divide up the main chamber into stalls - a feature typical of many of Orkney's stalled cairns. However, unlike most of these, which tend to be oblong or rectangular, Unstan is circular.
Entrance is through an approximately 25 foot entrance low passageway. Once inside the 27-1/2 foot main chamber, split into five sections by vertical slabs of flagstone - three central stalls and two shelved end-compartments -- the visitor can stand.
