The first 4 photos are from Villa Poppaea; Wikipedia tells us:
The
Villa Poppaea is an ancient Roman seaside villa (
villa maritima) situated between
Naples and
Sorrento, in southern Italy. It is also called the
Villa Oplontis or
Oplontis Villa A by modern archaeologists.
[1] The villa itself is a large structure situated in the ancient Roman town of
Oplontis(the modern
Torre Annunziata), about ten metres below modern ground level. Evidence suggests that it was owned by the Emperor
Nero, and it is believed to have been used by his second wife,
Poppaea Sabina, as her main residence when she was not in Rome.
[2]The rest of the photos are from Herculaneum. The famous Villa dei Papiri of which the Getty Villa is a copy is off limits to visitors.
