The Parco Nazionale del Circeo (English: National Park of Circeo) is an Italian national park founded in 1934. It occupies a strip of coastal land from Anzio to Terracina, including also a sector of forest in the mainland of San Felice Circeo, and the island of Zannone. The park was established by order of Benito Mussolini, under advice from Senator Raffaele Bastianelli, to preserve the last remains of the Pontine Marshes which were being reclaimed in that period. It is the only national park in Italy to occupy only a plain and coastal area.
