On our amble through Paris, we bumped into the Arc de Triomphe.

We climbed the tower (for a fee), and checked out the views of the city.
 

It’s right in the centre of Paris, smack bang in the middle of a massive, twelve street roundabout. The traffic on it is chaotic! There aren’t any marked lanes (although it could easily have about seven lanes) and the cars and mopeds just weave in and out. Its crazy! In this pic, the car facing the wrong way ended up reversing to find an exit.
