There is a brilliant version of Morgans map of 1682 at the Layers of London site; you need to click to use the overlay, then use the sliders on the Overlay tools to get varying images. I also hide all pins.
The Morgan map depicts the city of London 16 years after the Great Fire. This map complements the slightly earlier Ogilby and Morgan map by adding a survey of Westminster and a section of Southwark and showing the changes made to the city from 1676 to 1682. The Morgan map also includes detailed depictions of churches, markets, and great houses located throughout the area and a long panorama of London and Westminster. An original map survives in the British Library.
There is duplication of the numbering system amongst the four sections of the map.
There appear to be four sections of the key, which relate to different sections of the map.
The first is Westminster, and includes about 419 separate key entries, and many of thses are Inns (or Innes). Beginning in Portugal street (later named Piccadilly) and ending at 419 Bishops Head court in Grays Inn lane.
Here is part 1 of Westminster from St Thomas (1) to Walker yard (209)
