The Circus Maximus was the largest stadium in ancient Rome. At one point the Circus could seat 250.000 people, one quarter of Rome's population... Chariot races were one of the Roman's most popular form of entertainment. Romulus, the first of Rome's seven kings, is said to have held chariot races. The origins of the Circus Maximus go back to the 6th century BC when Tarquinius Priscus, the fifth king of Rome, created a track between the Palatine and Aventine hills. The first permanent starting gates were created in 329 BC. In 174 BC the gates were rebuilt and seven wooden eggs were placed on top of the spina, the central wall in the arena. The eggs were used to count the number of laps; after each lap one egg was removed. In 33 BC seven bronze dolphins were added to the spina for the same purpose.
