| Abstract: | The Tregiffian project involved the analysis and dating of the archive from unpublished excavations in the 1960s and 1970s at an entrance grave in Penwith, Cornwall. A major aim of the project was to establish a robust chronological basis for the use of the entrance grave for burial: 10 samples of cremated human bone were submitted for radiocarbon dating and Bayesian modelling undertaken. The modelling indicates that the use of the chamber for burial between began in 1780–1510 BC and ended in 1595–1425 BC. The results are hugely significant as they provide the first modelled dating from a Penwith entrance grave. This paper discusses the results from the radiocarbon dating project and reconsiders entrance graves in the wider context of the Early Bronze Age megalithic tombs which are found around the Irish Sea. |
