The Archaeology of Hinkley Point C Nuclear Power Station, Somerset. Excavations in 2012-16

A small cemetery dating to between the 5th and 7th centuries was revealed. Careful examination of the remains has revealed insights into burial practices.

The cemetery was excavated in its entirety and contained the remains of around 300 individuals. Its form is shown to have many characteristics in common with other cemeteries of this period in the western British Isles, including the extended, supine posture of the deceased in simple earth-cut graves largely aligned in a west/east orientation. There were a limited number and range of grave accompaniments. Peculiarities included a concentration of intercutting burials within a small central rectangle, with the later re-use of this space for the deposition of fragments of carved stone, followed by the construction here of a wooden building. The deposition of seashells with a number of the burials appears to be a rite so far unique to this community. The stratigraphic sequence allied to radiocarbon dates on 51 individuals has enabled an unusually refined chronology, showing that the cemetery was used from the early 5th to the later 7th centuries. Measurements of the isotopes of strontium, oxygen, carbon, nitrogen and sulphur in various combinations from a selection of individuals provides insights into aspects of origin, movement and diet. Mitochondrial DNA has provided information on the maternal lineage of 44 individuals, some of whom were buried in the same grave as others of the same lineage. Material remains were sparse but provide insights into the burial practices at this time.
