Anzio is a city and comune on the coast of the Lazio region of Italy, about 51 kilometres (32 mi) south of Rome.
Well known for its seaside harbour setting, it is a fishing port and a departure point for ferries and hydroplanes to the Pontine Islands of Ponza, Palmarola and Ventotene. The city bears great historical significance as the site of Operation Shingle, a crucial landing by the Allies during the Italian Campaign of World War II.
