The National Archaeological Museum Gaio Cilnio Mecenate is located in Arezzo and is located in the medieval monastery of Monte Oliveto. The monastery has ancient origins and stands on the ruins of the Roman amphitheater which is still partially visible on the first floor. The Museum was initially founded by the Fraternity of the Laity in 1823 as a museum of “Natural History and Antiquity”; only in 1973 was it bought by the state. The museum houses a very large collection with finds from the Etruscan and late antiquity found in excavations in the city and in the surrounding area. The Museum hosts special and thematic sections: paleontology, prehistory, early Middle Ages, precious ceramics and bronzes. The collection also includes donations from citizens of Arezzo such as Bacci, Gamurrini, Funghini and Ceccatelli. Among the most important finds of the Etruscan section are a polychrome frontal decoration with fighting scenes, the jewels of the necropolis of Poggio del Sole, decorative plates, votive statuettes of children in swaddling clothes and a large coin. The Roman section, on the other hand, includes mosaics, sculptures, inscriptions, funerary monuments, portraits and grave goods and mosaics. One of the novelties of recent years is the application that allows the visitor to enjoy the museum in augmented reality.
