 Identified in 1937 as one of the Severn-Cotswold type of megalithic chambered tomb, the cromlech was partly restored following an excavation during 1960–1961.North-West European lifestyles changed around 6,000 BP, from the nomadic lives of the hunter-gatherer, to a settled life of agricultural farming – the Neolithic Revolution.However, analysis of the human remains found at the cromlech show the tomb to have been accessed for up to 800 years and that the people interred within it continued to be either hunter-gatherers or herders, rather than agricultural farmers.
