Cambridge Archaeological Unit undertook a trenched evaluation on the R and D Land at Babraham Research Institute, prior to the development of this area. The trenching revealed limited archaeology towards the eastern half of the site, however towards the west significant Romano-British activity was identified. This included a large number of substantial ditches, a dark-earth deposit containing significant quantities of finds which possibly sealed earlier features, and a possible structure consisting of three parallel beam-slots. The evaluation also identified the extent and depth of the flood-plain alluvium deposits together with a paleochannel.
