This article from the Topographer is primarily a regurgitation of Leland with some additional notes: its most notable feature being an (exaggerated) illustration of the Watergate and the building later replaced by the Watergate Hotel. For a discussion of the image see this page. The building on the left hand side is probably the Ship and Castle Inn.
There is little new material gained in this description, although it is an interesting independent eighteenth century history of the town, uncoloured by Collinson’s History.
