The Colossus Neronis was an enormous, 30 m bronze statue that the Emperor Nero (37–68 AD) created in the vestibule of his Domus Aurea, the imperial villa complex which spanned a large area from the north side of the Palatine Hill, across the Velian ridge to the Esquiline Hill. It was modified by Nero's successors into a statue of the sun god Sol. It is last mentioned in the 4th century AD. The statue was eventually moved to a spot outside the Flavian Amphitheatre, which (according to one of the more popular theories) became known, by its proximity to the Colossus, as the Colosseum.
