The Colossus of Nero (Colossus Neronis) was a 30-metre (98 ft) 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 in Rome. It was modified by Nero's successors into a statue of the sun god Sol. 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. The last mention of the Colossus is in an illuminated manuscript from the late 4th century AD. The statue disappeared sometime afterwards, likely toppled by an earthquake or destroyed during the Sack of Rome. Today, the only remnants of the statue are some concrete blocks that once made up the foundation of its marble pedestal.
