The Cambridge Archaeological Unit (CAU) prepared a desk-based assessment for the site in Godmanchester in 2008, and trial trenching in the same year. The main site east of the A1198 was then excavated in 2014–15, and the final small areas to the west of the A1198 in 2020. The excavations revealed: • Neolithic pits and residual flints • an Early Iron Age pit alignment • a major Middle Iron Age boundary ditch which extended over 1.2 kilometres • an earlier Middle Iron Age open settlement by the pit alignment • a later Middle Iron Age enclosed settlement to the south, apparently occupied up until the Roman conquest for AD43 • a small Roman single-house settlement which was abandoned in the Early Roman period • Roman era-enclosures which survived into the Middle Roman period, and received a number of unusual inhumation burials—one of them accompanied by a dog and horse • Early Anglo-Saxon pot-built houses and sunken feature buildings, extending from a known settlement to the north under the business park site.
