What I kept finding myself wanting, however, was a 'historical' Google maps.

But the urban structure of Paris changed considerably in the 19th century. Baron Haussman's renovation of the streets of Paris in the 1850s and 1860s dramatically altered the fabric of the city, razing buildings and entire streets to make way for his network of boulevards. For an 18th century-ist, sometimes it's difficult to imagine what the city was like a hundred years earlier. Before the Louvre had its large symmetrical wings, for example, the area around the palace was made up of little residential streets with shops and churches, and before the quays of Paris became roads, they were functioning ports.

I've spent many hours in Paris wandering around streets with printed bits of Turgot's map trying to work out where things were... fun but not very effective. It gave me a great sense of the early modern city, but apart from lots of coloured annotations on bits of paper, no way of visualising it.
Bridging that disconnect between the 18th century and today - between Turgot's Paris and Google's Paris - became a lot easier a few months ago when Mia Ridge drew my attention to some fantastic sites which I've found both useful (as research tools) and inspiring (as visualisations of urban history research).

And if you're imagining how great it would be to have this on a mobile device with GPS, so you could wander quite literally through the streets of the past, then look no further than Look Back Maps, who have developed an iPhone app which locates historical data on contemporary maps (video demo). Another similar technological activation of historical geographies and archives is Philaplace, a local urban history project of Philadelphia using maps, photos and other data, which I've already blogged about here.
