Excavations at Chester. Roman land division and a probable villa in the hinterland of Deva reports on excavations carried out by Northern Archaeological Associates (NAA) at Saighton Camp – a former British Army training camp – located to the south of the Roman legionary fortress of Chester (Deva Victrix) which revealed important and extensive Roman period remains. Part of a high-status settlement of second- to fourth-century date, together with a regular field system laid out over more than 20 hectares, were encountered.
