Mount Vesuvius, the massive, active volcano that looms over the Bay of Naples and the Campania region, was responsible for the destruction of Roman towns Pompeii and Herculaneum in 79 AD. Vesuvius last erupted in 1944. Allied fliers took photos of the eruption. What we call “Vesuvius” is really the younger part of the mountain complex that geologists call “Greater Vesuvius”. The older part of the mountain, now an extinct volcano, is called Monte Somma. A fresco recovered from Pompeii shows a single summit and much taller Monte Somma covered in vegetation before the eruption of 79 AD. In 1995, the area around Vesuvius was formed into the Parco Nazionale del Vesuvio, the National Park of Vesuvius.
