Bronze Age Enclosures on land at rear of 16-20 Cambridge Road, Sawston, Cambridge (the Police Station site): An Evaluation and Excavation

An evaluation and excavation at a housing development behind Sawston Police Station revealed three elements of a large Bronze Age field or enclosure system. The enclosure had been recorded in a previous excavation immediately to the south during the first stage of development at the site in 2003, where it was interpreted as being of Roman origin. The ditches uncovered during this second phase of development were found to contain very large quantities of struck flint in their upper fills, possibly emanating from a knapping site on or close to a clearance cairn. The material dates to the second half of the 2nd millennium BC and appears to be the result of deliberate deposition. The struck flint assemblage was part of a much larger deposition of un-worked flint nodules. The upper fills of the ditches also contained a relatively small but varied faunal assemblage, with almost half the material being red and roe deer.
