The Circus Maxentius, which is situated on the Via Appia, was built during the reign of the emperor Maxentius (r. 306-312).
The track, which is 503 m long and between 75 m and 79 m wide, is one of the largest known.
The spina, the barrier running down the middle of the track, is exactly 1,000 Roman feet (296 m) long, and would have been cased in marble. The obelisk that now graces the Piazza Navona once stood on the spina.
