Anzio (/ˈænzioʊ/,[4][5] also US: /ˈɑːntsioʊ/;[6] Italian: [ˈantsjo]) is a town and comune on Lazio coast [it] region of Italy, about 51 kilometres (32 mi) south of Rome.

Well known for its seaside resorts, it is a fishing port and a departure point for ferries and hydroplanes to the Pontine Islands of Ponza, Palmarola, and Ventotene.

The town 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 February 1944 American soldiers (the U.S. Fifth Army) were surrounded by Germans in the caves of Pozzoli for a week, suffering heavy casualties.

On 18 February 1944, the British light cruiser Penelope was struck by two torpedoes off the coast of Anzio and sunk with a loss of 417 crew.

This tornado never received an official rating from the European Severe Storms Laboratory, however, the La Stampa newspaper wrote an article how it was “exceptionally violent”.

About 8 kilometres (5 miles) north of the town there is a WWF park with sulphur springs and a medieval tower, Tor Caldara.

Near the ruins of the Villa of Nero, in scenic position near the beach, lies the military sanatorium of the Italian Army, one of the most important works of Florestano Di Fausto, built-in 1930–1933.

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.
