Pompeii is a preserved ancient Roman city in Campania, Italy, at the southeastern base of Mount Vesuvius. It was built on a spur formed by a prehistoric lava flow. Pompeii was destroyed, together with Herculaneum, Stabiae, Torre Annunziata, and other communities, by the violent eruption of Mount Vesuvius in 79 CE. Miraculously, the circumstances of their destruction preserved the remains of the cities as well as its citizens and serves as a unique document of Greco-Roman life. Pompeii, was designated a UNESCO World Heritage site in 1997.
