The Domus Aurea
("Golden House") was a large palace
built by the Roman emperor Nero
after the fire that devastated Rome
. It was made of marble
and covered in gold
In the centre was a man-made lake, and Nero also commissioned a bronze statue of himself, designed to look like Apollo.
Vespasian tore down most of the Domus Aurea, and filled the lake with concrete, in order to build the Flavian Amphitheater.
