The Neolithic Barnhouse Settlement is sited by the shore of Loch of Harray, Orkney Mainland, Scotland, not far from the Standing Stones of Stenness, about 5 miles north-east of Stromness.

[3]: 52 Pottery of the grooved ware type was found, as at the Stones of Stenness and Skara Brae.

[5]: 32  Flint and stone tools were found, as well as a piece of pitchstone thought to have come from the Isle of Arran.

It was double-sized, featuring a higher building standard than the other houses and unlike the others was rebuilt up to five times.

[3]: 52 After Barnhouse ceased to be occupied, another structure was added, partially on top of the earlier building sites.
