The Romans were famous for building many structures, one of these being the giant building we now know today as the Colosseum. This colossal building was used by Romans as an arena where gladiators would spar, wild exotic animals were paraded, and "naval battles" took place.
The original name for the Colosseum was the Flavian Amphitheater because it was built when the Flavian dynasty ruled Rome. This giant building which was made of stone and concrete could fit 50,000 people in its chairs.
The construction of the Flavian Amphitheater began under the rule of Emperor Vespasian in the year 72 A.D. In the year 79 A.D. the third story of the giant building was finished just after the emperor died. The building was finished during the rule of the next emperor, Emperor Titus.
In 217 A.D. the wooden upper levels of the Colosseum were burnt up in a fire caused by a lightning strike, not being fully repaired until 240 A.D. and was fixed furthermore in the year 250 A.D. The Coliseum was 189 meters long, and 156 meters wide. The height of the wall was 48 ft. and the perimeter of the building was 545 meters thus making it one of the Romans' greatest engineering feats.
