Cornwall Archaeological Unit (CAU) undertook a programme of archaeological evaluation at Camel Creek Adventure Park, St Issey, Cornwall following a geophysical survey of the site (SUMO 2020). Associated planning application reference: PA19/00934. A total of 38 evaluation trenches were planned, of which 35 were eventually excavated. A total of 65 features were identified, the majority of which were undated but which included ditches, pits, postholes, stakeholes and possible ring gullies of probable prehistoric date as well as additional field boundary ditches of possible medieval and/or post medieval date. Some possible features associated with post-medieval mining and quarrying were also identified. Significant features identified include several areas of prehistoric activity indicating possible settlement or working areas, including possible roundhouse structures, along with potentially associated field systems and/or enclosures. Very little dating evidence was found to securely date features, although two pits containing probable Neolithic Grooved Ware were recorded in Trench 30, Area 3. Recommendations for mitigation include targeted areas of open area excavation or strip map and sample prior to any groundworks as well as watching briefs for the duration of any groundworks.
