When renovations were proposed for no 89 East Hill, the architects decided that there was a need to establish the course of the Roman town wall where it passed under the property, if possible. No trenches were possible in the house, so the investigation concentrated on the rear garden. Four trenches were dug, all located hard up against north brick boundary wall. Little of the town wall proved to survive in the garden, and possibly none survives under the house itself. The highest part of the property is the centre and rear parts of the garden, where the base of the wall foundation still exists (Trenches 3 and 4). Elsewhere, near the house (Trenches 1 and 2), the ground-level has been lowered to a point were even the base of the wall foundation has been removed. This fits in with East Hill??, since it seems that the gradient of the street was reduced on at least one occasion in the 18th or 19th century. The width of the wall shown on Figure 6 is based on measurements from elsewhere on the circuit. The east edge of the wall in Trenches 3 and 4 as shown in Figure 6 seems too far west if, as seems likely, this represents parts of the edge of the foundation. The explanation for the discrepancy may be related to the fact that there is a large difference in levels between the garden of no 89 and the gardens of the houses fronting onto Roman Road, and it is difficult to relate the areas accurately in plan. <1>
