Ottaviano is a comune in the Metropolitan City of Naples in the Italian region Campania, located about 20 kilometres east of Naples and is located in the Vesuvian Area. Ottaviano was in Roman times a hamlet of houses within a vast estate belonging to the gens Octavia, Augustus's family.
The territory of the country includes most of the crater of Vesuvius. The Medici Castle in Ottaviano houses the headquarters of the National Park of Vesuvius.
Ottaviano suffered significant destruction during the 1944 eruption of neighboring Mount Vesuvius. Now the city is home to the center office of Vesuvius National Park.
