Walworth from an important large-scale survey of London

Walworth, in the Borough of Southwark, with Walworth Road, the Old Kent Road and Grange Road. At the time of publication Walworth Common was open land; now it is completely developed.

Howgego describes Horwood's map as the 'largest and most important London map of the eighteenth century', on a scale of 26 inches to a mile. Horwood's intention was to mark each house's number (a practice started in 1735), but this was abandoned as impractical. He started his scheme in 1790, expecting to be finished by 1792: by 1794 he was apologising to his subscribers (including George III); in 1798 he received a loan of £500 from the Phoenix Fire-Office, for whom Horwood worked as a surveyor, to finish the map. However this assistance was not enough to stop Horwood dying in poverty in 1803.
