Archaeological and geoarchaeological work carried out in advance of development on land adjacent to Sentry's Farm, Exminster, Devon, was undertaken by AC Archaeology during March, April and October 2015. The site occupies approximately 1.7 hectares of pastoral land to the southeast of Exminster. It has been subject to a previous archaeological evaluation which identified a small number of largely undated archaeological features alongside an early medieval pit. The archaeological excavation comprised a 60m x 15m area, parallel with the southern boundary of the site. The geoarchaeological evaluation comprised the machine-excavation of a single 'T' shaped trench, totalling 49.5m in length and located in the east of the development area, between agricultural land and the edge of the Exe Estuary and was conducted to investigate the geoarchaeological potential of this marginal landscape. The combination of archaeological and geoarchaeological work across the development area has illustrated a complex history of deposition associated with long periods of arable cultivation alongside marine inundations throughout the historic period. The lack of archaeological features identified during the excavation phase confirms that the area was not extensively utilised for settlement, although the early medieval pit and cluster of mostly undated examples were recorded.
