This archaeological desk based assessment was commissioned by Bidwells on behalf of Christ’s College to assess the potential impact of a proposed development at 6-18 King Street, Cambridge (TL 4510 5866). Evaluation of selected archaeological, historical and cartographic evidence shows the proposed development area (PDA) to be located within an area of rich historical and architectural significance, dating from the Iron Age to the present day. Geotechnical investigation has confirmed that there exists a reasonable possibility of encountering artefacts and features dating from the Medieval period onward in areas that have not been severely truncated due to the construction of the extant and former buildings, with a lower probability of encountering Roman or earlier archaeology.
