A Roman bath house or Thermae, abandoned by the early 2nd century, has been discovered which had bricks stamped by the 2nd Legion, suggesting perhaps some kind of early military establishment on the site. There were certainly funerary monuments of persons of status at this early period, including a fine sculpted lion. The settlement later became a ribbon development of typical timber and stone strip buildings within ditched enclosures fronting a north-south Roman road. Industry included agricultural processing and large scale iron working. Occupation continued into the 4th century.
