It is a marvellous architectural complex that doesn't find examples in Roman art. Its real name is Flavian Amphitheater. It was built in 72 A.D. by an unknown architect.
Built by emperor Nero, it had to be the largest and richest residence ever raised. It was named Domus Aurea (gold House) thanks to its valuable decorations and prestigious furniture.
It has a very ancient origin but its actual shape dates back to the last years of the V century. In it you can admire the Mosè by Michelangelo which is a work of art, unique for its incomparable expressiveness and beauty.
