Domus Aurea



The Domus Aurea, meaning Golden House, was one of Nero's most notable projects. It was located between the Esquiline and Palatine Hills, and it was built on land that the Great Fire in 64 cleared out. It was extravagant, and it was decorated almost entirely in gold (hence the name). There was also, in front of it, something called the Colossus Neronis, which was a 120-foot high bronze statue of Nero that was right outside the entrance. After Nero's death, parts of it were opened to the public.
