The Isolotto di San Martino is a very small and incredible island of 1600 square meters, located in the municipality of Monte di Procida, which is accessed through a narrow tunnel and a wharf. Since 1917, however, was used as an industrial plant for the testing of torpedoes in the bay torpedo factory. In the 60s of the twentieth century the islet, granted to a private individual, has become a tourist attraction, offering tourists the opportunity to admire historical artifacts and a seabed to explore.
