Domus Aurea

Octagonal hall

Domus Aurea ("House of gold" in Latin, precisely because much of this precious metal was used in it) was the urban villa built by the Roman emperor Nerone after the great fire that devastated Rome in 64 AD. The destruction of a large part of the urban center allowed the princeps to expropriate a total area of about 80 hectares and to build a palace that extended between the Palatine, the Esquiline and the Celio.
