<P> The Villa of the Mysteries (Italian: Villa dei Misteri) is a well - preserved suburban Roman villa on the outskirts of Pompeii, southern Italy, famous for the series of frescos in one room, which are usually thought to show the initiation of a young woman into a Greco - Roman mystery cult . These are now probably the best known of the relatively rare survivals of Ancient Roman painting . Like the rest of the Roman city of Pompeii, the villa was buried in the eruption of Mount Vesuvius in 79 and excavated from 1909 onwards (long after much of the main city). It is now a popular part of tourist visits to Pompeii, and forms part of the UNESCO World Heritage Site at Pompeii . </P> <P> Although covered with metres of ash and other volcanic material, the villa sustained only minor damage in the eruption of Vesuvius in 79 AD, and the majority of its walls, ceilings, and most particularly its frescoes survived largely undamaged . Since its excavation the roofing and other parts of the house have been maintained as necessary . </P>
