In April 2015, Wessex Archaeology was commissioned by Richard Wood, Salisbury Cathedral Close Surveyor, to undertake a ground penetrating radar survey on land at Salisbury Cathedral, Salisbury, Wiltshire to gain information on the extent and character of a buried water culvert. This work was undertaken by Wessex Archaeology's in-house geophysical specialists. The high-resolution radar survey has revealed several sources of high-amplitude reflection readings of potential archaeological significance. Most relevant to this project are the clear linear high amplitude responses that represent the water culverts that are shown in historic mapping. Further responses are likely to represent past landscaping features and walls. The survey was undertaken on the 16th April 2014 with favourable weather conditions and ground underfoot.
