The Circus Maximus is an ancient Roman chariot racing stadium and mass entertainment venue located in Rome. Situated in the valley between the Aventine and Palatine hills, it was the first and largest Chariot Racing Stadium in ancient Rome. The site is now a public park and retains little evidence of its former use. The Circus could hold over 1/4 of the city's population, over 250,000 people, allowing for this Circus to be a popular viewing place by the Romans. The Circus measured "621 m (2,037 ft) in length and 118 m (387 ft) in width."
