The Citroën design center on Paris' Champs-Élysées lives up to its name! One of my favorite things about European cities is the architectural juxtaposition between old and new and the way they are often tightly integrated.

The art nouveau metro stops of European cities like Paris and Barcelona really set their style apart from the rest of the pack with their more modern, more legible and more boring alternatives. Look at that sign. What a great first thing to see when climbing the stairs from the underground tunnels of the metro. This particular stop is on the Louvre block so the background doesn't hurt, either.
