Ordnance Survey map of City of London (part) with Stepney, Limehouse, Bermondsey and the docks, published by the Ordnance Survey, Southampton 1851 (Sheet 21). On folding linen in 12 sections, size 40 by 27 inches, scale 12 inches to the mile or 1:5280. Reduced from the skeleton plans, surveyed and engraved by the OS under Captain Yelland 1848-51. The result of a survey designed to form the basis of a new set of maps of the capital prompted by concerns about public health and the lack of any accurate map of showing the levels of the area to be drained. Previous OS maps had not shown London in such detail. The map shows streets in outline and includes every street, railway and canal, with heights above sea level shown in hundreds of places. Covers an area from Finsbury Square across to Bow Common in the north and from the New Kent Road across to the Isle of Dogs in the south. Includes London Bridge. Evidence of old damp stains to reverse. Occasional foxing and fading. Good condition.
