Anzio is a city on the coast of the region of Lazio in Italy, about 51 kilometres (32 mi) south of Rome. Well known for its seaside harbor 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. In ancient times, Antium was the capital of the Volsci people until it was conquered by the Romans. Along the coast there are numerous remains of the Roman villas. The Domus Neroniana has been identified as a residence of Nero. About 8 kilometres (5 miles) north of the town there is a WWF park with sulphur springs and a medieval tower, Tor Caldara. All along the coast a large number of beaches and sea resorts can be found, including hotels and the famous fish restaurants of the port of Anzio. The city once hosted a Casino called Paradiso sul mare that is no longer active and now hosts cultural events.
