Situated on the premises of the fourteenth-century Cassero Senese at Grosseto, this small multimedia museum aims to stimulate the interest of young visitors in the city and its territory. Various thematic itineraries (a sound tunnel, a boat and the marsh, a bird-watching post) combined with interactive posts, provide a deeper knowledge of the historical, scientific and cultural aspects linked to the flourishing naturalist environment of the reclaimed land once covered by Lake Prile.
