Which of these locations corresponds to the modern-day city known as Arausio?

Arausio is the ancient name for the modern city of Orange, located in the Vaucluse department of southeastern France. This city is renowned for its well-preserved Roman architecture, including a magnificent Roman theatre and an impressive triumphal arch, which date back to its time as a significant Roman settlement.

The choice of Orange aligns with the history of Arausio as it served as a hub for the Roman province of Gallia Narbonensis. Acknowledging this connection illustrates an understanding of how ancient names often persist or evolve into modern city names.

The other locations mentioned do not share this specific ancient connection. Aquincum was a Roman city located in present-day Budapest, Hungary; the Colosseum is a famous amphitheater in Rome, and the Circus Maximus was an ancient Roman chariot racing stadium, also in Rome. None of these correspond to the ancient name Arausio.
