Lligwy Burial Chamber is located in Lligwy close to Moelfre on the east coast of Anglesey, Wales.
The burial chamber is a Neolithic dolmen, a single chambered tomb dating to around 3000 B.C. When it was excavated in 1909 the remains of about thirty people were discovered, these included the bones of children. Pottery was also discovered, these pieces helped to age the tomb.
The chamber consists of a ring of upright stones capped with a huge slab of rock, measuring eighteen by fifteen feet and weighing about 25 tons. It is thought that the dolmen would have been covered in earth or small stones with a low short tunnel to gain access inside.
