A useful resource for Victorian London

[ffutures]

This map superimposes Google maps and Victorian ordnance survey maps of London circa 1896. I've already found some interesting surprises in my local area, including a row of 50+ houses that was demolished to make room for railway lines some time between then and the 1940s.
