Archaeological excavations on land north of Wessex Close, Topsham, Exeter were undertaken in two phases between September 2015 and April 2017. Archaeological evidence on the site follows broadly from intermittent prehistoric settlement within largely agricultural land until the beginning of the Roman period, to planned and sustained occupation throughout the later 1st to early 4th centuries AD. The main interest in the site was the remains of a large stone-footed aisled hall of Romano-British mid-2nd century AD date. Part of a probable furnace room from a bath-house was also exposed along with a series of roadside and enclosure ditches, wells and ovens. The finds from the site include sherds of prehistoric pottery, largely Middle Bronze Age in date, but also including some Late Neolithic Grooved Ware, and worked flint. A large collection of Romano-British finds includes pottery, coins, metalwork (including jewellery), glassware, ceramic building material, slate tiles, stonework, metalworking remains and three cremation burials in pots. Environmental remains included spelt wheat and oats, while the presence of fish bones indicate that fish sauce was being produced on the site. More exotic items, such as remains of imported foodstuffs and imported pottery, show wide-ranging contacts in the 2nd and 3rd centuries AD adding to the evidence for a suspected port at Topsham. A small assemblage of medieval and post-medieval finds includes pottery from the known historic processing of sugar adjacent to the site.
