The Circeo National Park, is one of five national historic parks in Italy. It was established in 1934 by Mussolini to protect the last remnants of the Pontine Marshes, which in those years were reclaimed. It is the only Italian and European National Park to extend both plain and in a marine environment, and is a “biosphere reserve” by UNESCO since 1997. Located along the Tyrrhenian coast of Lazio, it is presented as a mosaic of different environments where the aridity of the dunes contrasts vast wetlands. Mount Circeo limestone is divided into two distinct areas: the northern slope covered with a forest of oaks and the southern slope exposed to bright sunshine all year round, rich in plants and Mediterranean shrubs. Among the mammals there are badgers, dormice and some species of bats; while among the birds there are the black redstart, the woodpecker and the peregrine falcon. Typical are the “pools”, swampy areas that are formed in the fall season for the accumulation of rainwater. In the territory of the park there is a sandy coastal strip that has a lush vegetation. The four coastal lakes of Paola, Caprolace, Monaci and Fogliano, are small pools of brackish water, ideal refuge for many species of waterfowl. In 1979, the Park has been enriched with a pearl of the sea: the Island Zannone which is uninhabited, covered with forests of oaks.
