The 5,000 year old monument, known as the Dwarfie Stane, lies in a steep sided valley, between Quoys and Rackwick, on the island of Hoy. A huge block of hollowed-out red sandstone measuring about 8.5 metres long. The Dwarfie Stane is thought to be Britain’s only example of a rock-cut tomb. It should be stressed, however, that not all archaeologists share this opinion. It is thought the chamber was carved out sometime between the Neolithic and the Early Bronze Age.
