The Colosseum: Project Facts

The Colosseum was built in eight years, 72 AD to 80 AD, in Rome, Italy during the reign of Roman Emperor Vespesian.

  • It had seating for 50,000 people and was designed with 76 different entrances each with their own seating areas for effective crowd control.
  • The Romans invented concrete and used it for the massive foundation which was an oval ring of concrete 167 feet (51 meters) wide and 40 feet (12 meters) deep.
  • A special ten-mile road was constructed from the quarry to the building site to accommodate 292,000 cartloads of stone needed to build the Colosseum.
  • Massive wooden frames were used to support the arches and vaults until all the stone parts were in place.
  • Huge linen veleriums hung from poles and ropes at the upper most levels and were moved by sailors to keep the audience protected from the hot sun.
