The Circus Maximus (or Circo Massimo) was one of the iconic structures of Imperial Rome. Along with the Colosseum, the stadium, used mainly for chariot-racing, was one of the most popular forms of entertainment for the city’s residents and in its heyday the stadium could hold over 250,000 spectators! Over the years the structures of the Circus Maximus have degraded substantially, but it’s definitely still worth a visit.
