A major commuter rail system in and around this city is the RER. Its current mayor is Bertrand Delanoe, and it is the only city to host both the Olympics and the World Cup twice. Due to height restrictions, the main core of this city is actually outside the city limits, in the La Defense neighborhood. Leading from that neighborhood through the center of this city is the "Grand Axis," on which is situated a monument to commemorate the Battle of Austerlitz. That structure, the Arc de Triomphe, lies at the western end of the Champs-Elysees. For 10 points, name this capital of France.
