Thanks to archeological research carried out during the twentieth century, the museum’s collections were significantly enhanced. The majority of these finds were the result of digs carried out inside the Accesa Etruscan territory (VI century) and included the excavation of houses and tombs. The exhibit spotlights a stele statue from the Neolithic period (III millennium BC) found in the Vada all’Arancio area as well as a cast fossil of Orcopithecus bambalii. Inside the museum, visitors will find two life-size grottos, which simulate a home and tomb; these installations occupy two rooms of the museum.
