St Lythans Burial Chamber - Siambr Gladdu Lythian Sant is a tall Neolithic tomb chamber with large capstone which would originally have been covered in earth and stone. The massive capstone is supported by three unusually tall uprights. It is located about two miles south of the village of St Nicholas, Vale of Glamorgan, South Wales (Welsh: Sain Nicolas, Bro Morgannwg, De Cymru) and about a mile south of Tinkinswood Burial Chamber.
