Skara Brae - the layout of the houses:

Skara Brae in the Orkney Islands is a village of ten one-roomed houses built between 2,500 and 2,000 years ago. Orcadian historian, Sarah Jane Grieve, takes us inside the village through its only entrance, along one of the narrow corridors, through the low doorway into one of the houses. She points out the design of the house around the central fire.
