The Roman name of the settlement has been lost, but there is evidence of buildings, a cemetery, occupation outside the town walls and a causeway across the Nene floodplain. A Romano-Celtic temple was recorded inside the town boundary. Square-shaped, it faced south-east; its outer "portico" measured 38 feet (11.5 metres) square and the inner "cella" about 17 feet (5 metres) square. The walls were around two feet (0.6 m) thick. The tombstone of a "Strator Consularis" – 'a transportation officer of the consular governor' – was also found at the town. An inscription found at Irchester offers evidence of organised horse-breeding.
