This interactive map shows how London looked back in the day

We all know the city has transformed quite a bit over the decades, but how much have these streets really changed? To see the real difference between back then and now, you can take a virtual walk down memory lane with a whizzy new map. Expedia's Historic London Map compares old snaps of the capital with current images taken from Google Street View.

Photos from the late 1800s and 1900s are placed on top of 14 different area backdrops, including Fleet Street, Stockwell and Oxford Circus, which looks as jam-packed as ever. Guess some things never change...

Have a play around with the map here.
