Evaluation by S Dyer of SCAU for Owens Galliver Architects, of an area proposed for redevelopment, revealed a ditch containing 15th century pottery running at right angles to the street frontage. It seems likely that this represents the division between two formally laid out burgage plots, which were not actually built on until much later. A subsequent watching brief recorded more of the ditch but no further evidence for its date or purpose was found. (289)
