A Roman building, probably a villa, is indicated by numerous finds made at Windmill Hill, Capel St Mary from the 1920s onwards. Excavations have uncovered building foundations, a courtyard, painted wall plaster, opus signinum, window glass and glass vessels, the remains of a kiln (possibly a glass kiln rather than a pottery kiln), tesserae, flue tiles in a pit overlying a wooden water channel, a coin of Hadrian, a pair of bronze crouching lions, and roofing tiles. Many Roman finds from the site are in Ipswich Museum (accession number 963-53-4; 967-89). Other Roman finds have occurred in the vicinity (TM 03 NE 8, 9). During examination of the site in 1949, fragments of three Middle Bronze Age pottery vessels were found. These are in Ipswich Museum (accession number 1947-4).
