Ercolano is a town and comune in the province of Naples, Campania (Italy). It lies at the western foot of Mount Vesuvius, on the Bay of Naples, just southeast of the city of Naples. The medieval town of Resina was built on the volcanic material left by the eruption of Vesuvius (AD 79) that destroyed the ancient city of Herculaneum, from which the present name is derived. Ercolano is a resort and the starting point for excursions to the excavations of Herculaneum and for the ascent of Vesuvius by bus.
Ercolano is connected to Naples through the Circumvesuviana regional railway, by bus and by Sea metro service.
