The construction of the Wickham Market bypass (A12) in Suffolk provided the opportunity to investigate more fully a Roman `small town' already known through fieldwalking, small-scale investigations, chance finds and metal detecting activities. This report publishes the findings from the 1973-74 geophysical survey and excavations at the site. The introduction provides a background history to the site which was first occupied before the Roman invasion and subsequently developed until the 4th century when it was abandoned. Evidence for pottery manufacture and ironworking were detected from the nature and quantity of finds which are reported here alongside the coins, small finds and zoological data.
