Tregiffian Burial Chamber is a Neolithic or early Bronze age chambered tomb. An entrance passage, lined with stone slabs, leads into a central chamber. It is located near Lamorna in west Cornwall, England, United Kingdom.
In 1999 there was some controversy regarding this site and others under the care of the English Heritage organisation. Members of a pressure group, the Revived Cornish Stannary Parliament, confiscated several signs bearing the English Heritage name. Since this action several of the smaller sites such as Dupath Well, The Hurlers (stone circles), Tregiffian Burial Chamber, St Breock Downs Monolith, King Doniert’s Stone, Trethevy Quoit and Carn Euny have been transferred to the care of the Cornwall Heritage Trust.
