The box below shows Horwood’s Plan annotated with all of the site’s current markers drawn from guides to London. These are Samuel Fores’s New Guide for Foreigners (the green and brown markers), Richard Phillips’ Modern London (the grey and orange markers) and Rudolph Ackermann’s Microcosm of London (the blue markers). More information on each of these guides can be found in their respective sections of the site (linked from the top toolbar). The different sets of markers can be added to or removed from the map using the control box in the top right. Full screen mode (activated using the button under the zoom controls) is particularly useful for getting a good perspective on this map.
