Thetford Town OCN Project: Thetford Grammar School, Report on Geophysical Survey, July 2024
Author(s): Megan Clements, Neil Linford
A vehicle-towed Ground Penetrating Radar (GPR) survey was conducted over an area of 4.3ha covering the playing fields of Thetford Grammar School, Thetford, Norfolk, as part of the Thetford Town Old County Number (OCN) Project. The aim of the project is to investigate a number of OCN designations within Thetford that will allow Historic England’s East of England Regional Team to make decisions regarding the management of the sites. The survey successfully revealed evidence for structural remains across the site associated, in part, with the known location of St John’s church and burial ground. More fragmented, possibly structural remains, corroborated results from an earlier GPR survey conducted in the vicinity of the current pavilion. However, extending the GPR survey over the entirety of the playing fields has revealed further significant building remains, possibly indicative of a small church or chapel, and a more complex group of anomalies associated with a substantial sub-circular structure approximately 20m in diameter. Linear anomalies found in the south-east of the site suggest the location of the Saxon town defensive ditch that potentially pre-dates some of the structural remains revealed by the survey. The field work was conducted in July 2024.
