where did the roman chariot races take place
Chariot racing In ancient Rome, chariot races commonly took place in a circus.[30] The main centre of chariot racing was the Circus Maximus in the valley between Palatine Hill and Aventine Hill,[f] which could seat 250,000 people.[27] It was the earliest circus in the city of Rome.[30] The Circus supposedly dated to the city's earliest times,[g] but Julius Caesar rebuilt it around 50 BC to a length and width of about 650 metres (2,130 ft) and 125 metres (410 ft), respectively.[31] One end of the track was more open than the other, as this was where the chariots lined up to begin the race. The Romans used a series of gates known as carceres, equivalent to the Greek hysplex. These were staggered like the hysplex, but in a slightly different manner since the center of Roman racing tracks also included medians (the spinae).[32] The carceres took up the angled end of the track,[33] where -- before a race -- the chariots were loaded behind spring-loaded gates. Typically, when the chariots were ready the emperor (or whoever was hosting the races, if outside of Rome) dropped a cloth known as a mappa, signalling the beginning of the race.[34] The gates would spring open at the same time, allowing a fair start for all participants.
Colosseum The Colosseum or Coliseum (/kɒləˈsiːəm/ kol-ə-SEE-əm), also known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium; Italian: Anfiteatro Flavio [aŋfiteˈaːtro ˈflaːvjo] or Colosseo [kolosˈsɛːo]), is an oval amphitheatre in the centre of the city of Rome, Italy. Built of travertine, tuff, and brick-faced concrete,[1] it is the largest amphitheatre ever built. The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in AD 72,[2] and was completed in AD 80 under his successor and heir Titus.[3] Further modifications were made during the reign of Domitian (81–96).[4] These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius).
