Oplontis is an ancient Roman archaeological site in Torre Annunziata, south of Naples, buried by the eruption of Mount Vesuvius in 79 AD. The site comprises two villas: Villa A (Villa Poppaea), a luxurious residential complex from the mid-1st century BC possibly owned by Nero's wife Poppaea Sabina, and Villa B, a commercial center for wine and oil production. Villa A features exceptional frescoes and a massive 60x17m swimming pool. The remains of 54 people were found in one room, trapped while awaiting escape from the eruption. Oplontis is inscribed as a UNESCO World Heritage Site alongside Pompeii and Herculaneum.
