Hadrian's Wall, Westgate Road, Milecastle 4

Stone foundations, interpreted as part of a milecastle, were uncovered in 1985 in the yards behind 67-75 Westgate Road. They consisted of flagged foundations 2.90 m wide, part of the first ashlar course and some of the core of the second, and together formed the south-west corner of the structure. A possible position of a south gate was identified 6 m east of the internal corner. No floor or occupation surfaces were found, and the ruins were sealed by a layer containing 2nd century pottery. This was probably a long-axis milecastle dismantled before the end of the 2nd century.
