Exploratory trenches were dug in part of the Britannia Works site which lies outside the scheduled area. This was done to determine whether the remains of the monastic buildings extended outside the scheduled area, and if these, or any other features, would be damaged by redevelopment. Two foundations with adjacent floors, presumably belonging to the priory, were located immediately to the south of the scheduled area at a depth of c. 1-1.4m. In the same area, waterlogged remains were also observed at a depth of 2m. No other archaeological features were found, due to the substantial depth of topsoil and the presence of underground chambers forming part of the Britannia works. <1>
