Just to the west of Peterborough lies the Roman town of Durobrivae. This town is one of the so-called ‘small towns’ of |Roman Britain and extended to 44 acres within the walled area. Until recently the only detail we had of the interior of the town was from air photographs and very limited 19th century excavations and recordings made by Edmund Artis. At the end of the summer of 2016 however, a team of people from Cambridge University, London University and the NVAT undertook a detailed set of geophysical surveys to see how the ground and its hidden archaeology would respond to various electronic, magnetic and radar surveys. The results from this pilot study were astonishing.
