The [David Rumsey Map Collection] (https://www.davidrumsey.com/) is superb for looking up specific maps from specific time periods - hopefully you should be able to find what you're looking for there!

Also - it's a bit more modern, but one map that absolutely fascinates me is the National Library of Scotland's digitalised [Ordnance Survey map of London from the 1890s] (https://maps.nls.uk/geo/explore/#zoom=10.0&lat=51.53214&lon=-0.12000&layers=188&b=1). It's incredibly detailed and shows you on a street-to-street level what London looked like 130 years ago. Plus, they also have a similarly detailed OS map of the city from the 1950s/60s, which lets you see how much the city changed over 60-70 years.
