Unknown among these known, the Excavations of Oplontis in Torre Annunziata (Naples), included in the fantastic complex of the more famous Pompeii and Herculaneum, admitted in the UNESCO list in 1997. The ancient Oplontis often goes unnoticed by the ruins visitors and tourists. It rises into the city centre of Torre Annunziata. In the past, it was a suburban area of Pompeii, where the wealthy Roman patricians used to go to have rest: it was a kind of holiday resort. 

The excavations include two villas: one for the Otium (leisure), which was probably of Poppaea (the second wife of Nero) and a second one more rural, known with the name of Villa B (finally open to visitors), which probably owned to Lucius Crassius Tertius, name founded on a bronze seal excavated in the building area.
