The site was first excavated in 1929 and was reinvestigated between 1985 and 1990. Finds from the site include a large number of flint tools, decorated pottery fragments and broken querns.
This Neolithic passage grave was built around 6,000 years ago (4000-3250BC). It consists of a passage leading into an unusual chamber which was originally ‘D’ shaped but later extended to produce a large open rectangular chamber.
