Final answer:
Roman spectators watched chariot races at the Circus Maximus, which was distinct from the Colosseum that hosted gladiatorial battles and other entertainments.
Step-by-step explanation:
Roman spectators watched chariot races at the Circus Maximus. While the Colosseum, also known as the Flavian Amphitheater, was used for gladiatorial contests, mock sea battles, and other forms of entertainment, it was not the venue for chariot races.
The Circus Maximus was specifically designed for this purpose, and it was a massive structure that could accommodate over 80,000 spectators, making it an essential feature of the city's social and sporting life.
