The Colosseum, originally known as the Flavian Amphitheater, was a gift to the Roman people. It was built on the site of an artificial lake, part of Nero's vast Domus Aurea complex. The decision to build the Colosseum here was symbolic, returning to the people an area Nero had claimed for his own opulent use.

Funding for its construction came from the spoils taken from the Jewish Temple after the Great Jewish Revolt in 70 AD. Thousands of Jewish prisoners were brought to Rome and likely contributed to the labor force.

Over the centuries, the Colosseum suffered damage from earthquakes and stone-robbers. Much of the fallen stone was reused to build other edifices throughout Rome. Despite this, it remains a powerful symbol of Roman imperial power and an architectural marvel.

The Colosseum is an elliptical structure, measuring 189 meters long and 156 meters wide, with an outer wall height of 48 meters. It was constructed from travertine limestone, tuff, and brick-faced concrete.

The arena itself measured 87 m long and 55 m wide, and was covered with a wooden floor topped with sand (the Latin word for sand is *harena* or *arena*). Beneath the arena was the hypogeum, an elaborate two-level subterranean network of tunnels and cages where gladiators and animals were held before contests began. Vertical shafts provided instant access to the arena for animals and scenery.

The seating was divided into tiers that reflected the rigidly stratified nature of Roman society. Special boxes at the north and south ends were reserved for the Emperor and the Vestal Virgins, respectively. Senators occupied the seats closest to the arena, while the higher levels were for lower classes and women.
