Tinkinswood is a wedge-shaped cairn, dating back to around 4000BC. The limestone capstone is around 24 feet by 15 feet, weighs roughly 36 tonnes, and is believed to be the largest in Britain. Originally, the tomb would have been covered by a mound, extending to the rear of the monument.

Various legends are associated with Tinkinswood, including the story that anyone spending the night here preceding May Day, St John's Day or Midwinter day would either die, be driven mad, or become a poet.

Tinkinswood is protected to a degree by its distance from the road, but conversely, this also makes a popular drinking spot for people from the surrounding area. There is frequently evidence of small parties, gatherings or overnight stops here.

Despite this, Tinkinswood is an impressive monument - distinctive in character and visually striking. The immense capstone can't fail to make an impact on anyone seeing it for the first time. The overhead powerline does, however, detract from the ambience of the site.
