Wessex Archaeology were commissioned to undertake an archaeological evaluation to inform a planning application for a proposed residential development on land to the rear of 182 High Street, Tonbridge, Kent. Six trenches were opened to clarify the presence or absence of remains associated with the Medieval town defences known as The Fosse. Two sherds of pottery found dated to the late 12th to 13th century and 13th to 14th century were found but the finds could be residual. The bank deposits were underlain by a layer containing quantities of charcoal and fragments of slag. This layer also produced 12th to 13th century pottery sherds. No cut features of archaeological significance were found. A shallow linear feature, a small pit and walls of modern date were revealed in some trenche along with services trenches. Made ground was revealed in one trench to depth of 1.7m+ and confirmed the presence of a pond, recorded on the 1838 tithe map.
