Circus Maximus

The Circus Maximus was a building in Rome. After mistakenly landing in Pompeii instead of Rome, the Tenth Doctor was confused by the lack of this building, as well as the Colosseum and the Pantheon. (TV: The Fires of Pompeii)

In an alternate Rome, aliens competed against each other at the Circus Maximus in chariot races. Magog and General Ironicus watched them from the Imperial Box. (COMIC: Doctor Who and the Iron Legion)
