sergio is my name. im a gay

How lovely for you, Sergio. Now to answer the question which was asked, chariot races were held in the Circus Maximus. The naval battles and gladiator battles were held in the Flavian Amphitheater, commonly known today as the Coliseum, first used in 80 AD. Before then, they were held in two smaller amphitheaters which continued to be used after the Coliseum was built. The Coliseum has been in ruins for centuries, but it is still a popular tourist attraction for visitors to Rome today
