This collection comprises a report and vector, GIS, and geophysics data from a magnetometer survey at Wiveliscombe Roman Fort, Wiveliscombe, Somerset. This work was undertaken by SUMO Geophysics in August 2023.

The magnetometer survey has recorded numerous magnetic responses that have been interpreted as being of archaeological interest. Several parallel linear anomalies on the northern limit of the fort are associated with defensive ditches, however, two of them extend away from fort and could be associated with different phases of activity. A rectangular enclosure is visible in the fort which measures 50 x 40m. Other linear and curvilinear anomalies, including two tentative ring ditches and pit-like responses of archaeological interest, have also been plotted in the survey. Weak pit-like responses in the north of the survey area have been assigned to the category of uncertain, however, they could be due to deeply buried ferrous debris. Two former field boundaries have also been plotted in the survey.
