The State Archaeological Museum, founded in 1996 through the joint efforts of the Archaeological Superintendency for the Marche and the Municipal Administration, is housed in a number of restored and modernised rooms of the monumental complex of S. Francesco, in the historic centre of Arcevia. The museum is laid out in three main rooms, where the finds follow one another in chronological order. The first displays the lithic industry artefacts from Ponte di Pietra (20,000 years ago), dating to the Upper Palaeolithic: worth seeing are the flint tools and the reconstruction of an archaeological layer exactly as it appeared to the excavators. The second room displays the material from the famous defensive ditch of Conelle (4th millennium BC), dating to the Eneolithic (the site can be visited and has information panels): among the ceramic products on display, the dolia and the ollae with applied plastic decoration stand out, as do the typical jugs with an oblique-rimmed spout. The third room features various items from Cava Giacometti and, above all, from the site of Monte Croce-Guardia, dating to the Final Bronze Age (12th-10th century BC), including a fine biconical vessel for funerary use and particularly fine decorative bone work. The last part of the exhibition is devoted to the Gallic cemetery (4th-2nd century BC) and to the sanctuary of Montefortino: the grave goods of the two tombs on display in the Arcevia museum and in the New York museum are splendid.
