WARNING: The following website may consume hours of your life!

It’s France Telecom’s Yellow Pages site which puts other online maps to shame. Rather than looking at colourful lines and dots, you can take a virtual stroll through 9 of France’s largest cities. Select your city of choice then zoom in to view photos of thousands of buildings.

And if you get bored of France, head down to Spain for a tour of Madrid, Barcelona, Seville or Valencia.
