Construction, inauguration, and Roman renovations
[ edit ] Sestertius of Titus celebrating the inauguration of the Colosseum (minted 80 AD). A map of central Rome during the Roman Empire, with the Colosseum at the upper right corner The site chosen was a flat area on the floor of a low valley between the Caelian , Esquiline and Palatine Hills , through which a canalised stream ran as well as an artificial lake/marsh. By the 2nd century BC the area was densely inhabited. It was devastated by the Great Fire of Rome in 64 AD, following which Nero seized much of the area to add to his personal domain. He built the grandiose Domus Aurea on the site, in front of which he created an artificial lake surrounded by pavilions, gardens and porticoes. The existing Aqua Claudia aqueduct was extended to supply water to the area and the gigantic bronze Colossus of Nero was set up nearby at the entrance to the Domus Aurea. Although the Colossus was preserved, much of the Domus Aurea was torn down. The lake was filled in and the land reused as the location for the new Flavian Amphitheatre. Gladiatorial schools and other support buildings were constructed nearby within the former grounds of the Domus Aurea. Vespasian's decision to build the Colosseum on the site of Nero's lake can be seen as a populist gesture of returning to the people an area of the city which Nero had appropriated for his own use. In contrast to many other amphitheatres, which were on the outskirts of a city, the Colosseum was constructed in the city centre, in effect, placing it both symbolically and geographically at the heart of Rome. Cross-section from the Lexikon der gesamten Technik (1904) Construction was funded by the opulent spoils taken from the Jewish Temple after the First Jewish–Roman War in 70 AD led to the Siege of Jerusalem . According to a reconstructed inscription found on the site, "the emperor Vespasian ordered this new amphitheatre to be erected from his general's share of the booty." It is often assumed, as it is with many other Roman projects at the time, that slaves and prisoners of war were brought back to Rome and contributed to the massive workforce needed for the construction of the amphitheater.
