In 1984 the entrance grave at Bosiliack, Cornwall, was excavated by Charles Thomas on behalf of the Institute of Cornish Studies. It was a comparatively small example, approximately 5 m in diameter encircled by a substantial kerb. A deposit of cremated bone was found within the chamber accompanied by sherds of plain pottery from three vessels. Two radiocarbon determinations were obtained on the cremated bone. The dates were almost identical, falling between 1690 and 1500 cal bc.
Because Bosiliack is the only entrance grave in Cornwall to have been excavated to modern standards, and to have had any analyses undertaken on the contents of its chamber, it is significant to the study of small chambered tombs elsewhere. This paper outlines the results from the excavations before moving on to a discussion of the use of monument and a consideration of its possible affinities with monuments elsewhere.
