1. Pompeii Archaeological Site is an ancient Roman city that was destroyed by the eruption of Mount Vesuvius in 79 AD and preserved under a thick layer of ash and pumice. It was rediscovered in the 18th century and is now a popular tourist destination with approximately 2.5 million visitors each year.
