Construction began around 70 AD in a low lying area between the Palatine, Esquiline, and Caelian hills that had once formed the pond of Nero’s Domus Aureus. The ampitheatre probably came to be called the “Colosseum” because a colossal statue of Nero once stood near it. The Colosseum was completed in 80 AD and seated more than 50,000 spectators.
