The Flavian Amphitheater
The Colosseum is probably the most impressive building of the Roman Empire. Originally known as the Flavian Amphitheater, it was the largest building of the era.
The monumental structure has fallen into ruin, but even today it is an imposing and beautiful sight.
Emperor Vespasian, founder of the Flavian Dynasty, started construction of the Colosseum in 72 AD. It was completed in 80 AD, the year after Vespasian's death.
The huge amphitheater was built on the site of an artificial lake, part of Nero's huge park in the center of Rome which also included the Golden House (Domus Aurea) and the nearby Colossus statue. This giant statue of Nero gave the building its current name.
