The beginning of monolithic monumentality in Europe is of outstanding significance and its accurate dating a consummation devoutly to be wished. In this case study from England, the researchers had the good fortune to find monoliths stratified above and below by peat and so were able to give them a bracketed radiocarbon date and an environmental context. The results show that the stones, belonging to a linear alignment of eight others, were erected in a clearing of heathland in the fourth millennium BC. The date raises the possibility of a Neolithic appearance for this type of stone row in south-west Britain and Britanny.
