Constructed nearly 6000 years ago, some 1000 years before Stonehenge, Tinkinswood Burial Chamber - Siambr Gladdu Tinkinswood is an impressive Neolithic dolmen. A huge 40 ton capstone, thought to be the largest in Europe, covers a rectangular burial chamber with a dry stone wall forecourt. When excavated the chamber held the bodies of over 50 individuals, along with broken pottery and worked flint. Originally it would have been covered by an earthen mound. It is located about a mile from St Nicholas (Sain Nicolas) in the Vale of Glamorgan, South Wales (Bro Morgannwg, De Cymru).
