The Arc de Triomphe is a location used in Rhythm Thief & the Emperor's Treasure. It is connected to Washington Avenue. In Chapter 5, Raphael and Marie head here in order to board a bus to the Palace of Versailles. However, the bus, owned by Noël, is broken, so Raphael helps fix it.

The sound disks for Phantom Fondue and Enter the Waiter can be found at the Arc de Triomphe, as well as the bus sound.
