Seashells from different parts of the world;phytoplankton images;sea sponges;crustaceans;sea urchins and a large Mediterranean aquarium are the treasures of the Museo del Mare e della Costa (Sea and Coast Museum);whose mission is to promote the knowledge of the Pontino coast and sea to the south of the Lazio Region.A nature itinerary includes an exhibition of fossils from the territory and virtual reproductions that allow visitors to imagine life during the Quaternary era;and an important classical archaeology section.Human activities connected to the sea are well documented;with a reproduction of the shipwreck of a Roman ship sunk off the coast of Sabaudia;and an exhibition of amphorae;vases and navigation equipment;as well as materials such as rings and coins that draw their artistic inspiration from the sea.The last fragment of Italy’s largest plain forest is protected by the National Park of Circeo;which includes the homonymous promontory.Closer to the sea;there is a long coastal dune that separates the coast from four salty lakes;rich in fish and aquatic birds.At the Park’s headquarters in Sabaudia;there is the Visitors Centre and a nature Museum.
