Just a few miles from Naples, near Pompeii, today's town of Torre Annunziata is the site of Oplontis -
where Nero's second wife is believed to have had a villa, adorned with Pompeian Style II wall paintings.

(The lady is variously referred to as Sabina Poppea, Poppaea Sabina and Poppaea Augusta Sabina)

You may also be able to find a fine work about the Villa, prepared by Colin.J.Andrews M.A.

Last time I looked, the official website had further photos here
