The main chamber is open and surrounded by a series of small stone cists (boxes) while the end chamber is covered by a massive 24-ton capstone. Human remains were found in the cists and finds from the chamber include pottery vessels, two polished stone axes and two stone pendants.
This Neolithic passage grave was built around 6,000 years ago (c. 4000-3250 BC). It consists of a passage leading into an unusual double chamber.
