Using image overlays it is possible to compare cities over time. The above and below images illustrate the layout of London in 1690 - post Fire of London - in Google Earth. It is interesting to note when changing the transparency how the shape of the Thames has been modified with the building of Embankment. 
You can download the kmz file to fly into the overlay in Google Earth here
