Excavation (1977) by K. Crouch for LAMAS and DOE produced 1st and 2nd century AD gravel workings and parts of three RB timber buildings on the National Provincial Bank site; a RB gully and general Saxon gullies, one reused in the 10th/Ilth century; and possibly pre-Flavian ditches and timber building, the latter demolished and replaced by others by the end of the 1st century. These in turn were demolished c130 and replaced by a masonry building, with further construction in the 2nd century, apparently no occupation in the 3rd and further activity in the 4th. Two early Saxon pits were covered by black soil containing late Saxon to 16th century material. A late pipe kiln was also discovered. (London Archaeol 3, 180-6)
