A watching brief was held during renovations to the ground floor structure of No. 21 Eld Lane. Two trenches (0.6m deep) were dug in the cellar floor and the Roman wall was exposed.<1> In 1989, the core of the town wall was exposed in the south-west corner of the cellar under no 21 Eld Lane when a hole was made in the cellar wall during refurbishment works. When the wall was being recorded, it was noticed that part of the north (ie the inner) face of the town wall was incorporated in one of the walls of the adjacent cellar under no 22. The position of the face could only be plotted to within ± 0.8 m north to south on the site plan, because the thickness of the cellar wall could not be determined. <2>
