Tinkinswood

Tinkinswood or its full name Tinkinswood Burial Chamber (Welsh: Siambr Gladdu Tinkinswood), also known as Castell Carreg, Llech-y-Filiast and Maes-y-Filiast, is a megalithic burial chamber, built around 4000 BC, during the Neolithic period, in the Vale of Glamorgan, near Cardiff, Wales. The structure is a dolmen, which was the most common megalithic structure in Europe. The dolmen is of the Severn-Cotswold tomb type, and consists of a large capstone on top, with smaller upright stones supporting it. The limestone capstone at Tinkinswood weighs approximately 40 long tons and measures 24 feet (7.3 m) x 14 ft (4.3 m); it is thought to be the largest in Britain, and also in Europe. It would have taken some 200 people to lift the stone into the correct position. It was originally all covered by a mound of soil, which has been removed over time. The remaining mound behind the structure measures approximately 130 ft (40 m) x 59 ft (18 m) in size.
