The Coliseum, also known as the Flavian Amphitheatre, was not built by Nero for the patricians on lands he seized from private citizens. It was actually commissioned by Emperor Vespasian and later completed by his son Titus around 80 AD. The Coliseum was a venue for various events, including gladiator contests, animal hunts, and mock naval battles; it could indeed be flooded for these naval battles.
