Mount Vesuvius is a stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 kilometers east of Naples and a short distance from the shore. It is one of several volcanoes which form the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier and originally much higher structure. The volcano is the only volcano on the European mainland to have erupted within the last hundred years, though it is currently dormant. Its most famous eruption took place in the year 79 AD when it destroyed the cities of Pompeii and Herculaneum. The Vesuvius has a significant place in history and culture and today is a popular tourist attraction. The surrounding area is a national park and tourists can hike to the summit, which offers views of the Bay of Naples and the surrounding landscape.
