Barpa Langass (also known as Langass Barp or Langash Barp; Scottish Gaelic: Barpa Langais[ˈpaɾpəˈl̪ˠaŋkɪʃ]), is a Neolithicchambered cairn on the Isle of North Uist in the Outer Hebrides of Scotland. It measures about 72 feet in diameter by 18 feet in height, and is around 5,000 years old.[1] The roof is constructed of two massive slabs with a third slab superimposed.
The entrance is at the east side. Although the structure has partially collapsed, it is still possible to enter one chamber. The antiquaryErskine Beveridge believed that a second and perhaps a third chamber exist. In or prior to 1911, Dr Beveridge excavated within and near the cairn, and he found evidence of burnt burials as well as pieces of pottery (some with patterned lines), wood ashes, burnt bones, a flint arrowhead, a scraper, and a piece of pierced talc.[2]
