Pompeii is a ruined and partially buried Roman town-city near modern Naples in the Italian region of Campania, in the territory of the comune of Pompei. Along with Herculaneum, its sister city, Pompeii was destroyed, and completely buried, during a long catastrophic eruption of the volcano Mount Vesuvius spanning two days in 79 AD.
The volcano collapsed higher roof-lines and buried Pompeii under 60 feet of ash and pumice, and it was lost for nearly 1,700 years before its accidental rediscovery in 1748. Since then, its excavation has provided an extraordinarily detailed insight into the life of a city at the height of the Roman Empire. Today, this UNESCO World Heritage Site is one of the most popular tourist attractions of Italy, with 2,571,725 visitors in 2007.
