The destruction of a 16th century building in April 1967 made the site available for excavation prior to its redevelopment for offices. The cellars of the building had destroyed all earlier occupation whilst west of the building; the garden soil had been disturbed down to Roman levels. The area available for excavation was severely restricted by the contractors and by safety considerations. Initially three trenches were opened up covering an area 43 feet west of North Hill and 10 feet north of the boundary with 45 North Hill. Further extensions were then dug to the west and south in an attempt to locate the limits of the Roman masonry building revealed by the first three trenches.<1> An architects plan in the SMR file shows the location of the excavation trenches but the orientation of these is different on the published version. <2>
