In the summer of 1952 a trench, coded C XXII K, was dug on the site of 53 King Street. A sucession of floors, occupation-levels and pits of Roman, Medieval and post-Medieval were discovered. The trench was divided by NE to SW brick partition, 15cm wide, and to the NW of this strip 46cm wide was left unexcavated.
Evidence included a Roman building with at least two phases of occupation and traces of possible iron production. Occupation of the site was shown to be continuous from the mid second century to some point in the fourth; and thereafter occupation resumed from late Saxon to modern times.
