The beautiful sea waters surrounding Capraia and Pianosa, two of the islands that make up the Tuscan Archipelago in the midst of theTerrenian Sea, hide in their depths historical and naturalistic treasures of incalcuble worth. Capraia is an island of lava and vulcanoes and lies furthest from the Tuscan coastland; famous as a prison island, it is now taking steps towards recuperating its long-abandoned areas of interest. The building that was once called “The Salata” where prisoners used to prepare anchovies, is now being used as a Tourist Information Centre for people visiting the National Park of the Tuscan Archipelago. Whereas Pianosa, which only looks like a strip of sun-baked land, actually preserves within its boundaries relics of pre-historic life, objects relating to man from the very ancient past. The purity of the air and the distance of the island from all forms of pollution, make Pianosa an exceptional laboratory for the study of global changes. The sea, protected in the past by the presence of its penal colony, and today by its National Park, is a tapestry of grottoes, ravines and cliffs all teaming with life.
