 Remains of the later prehistoric age have been found in Lombardy (stone carvings in Valcamonica) and in Sardinia (nuraghe).The most famous is perhaps that of Ötzi the Iceman, the mummy of a mountain hunter found in the Similaun glacier in South Tyrol, dating to c. 3400–3100 BC (Copper Age).During the Copper Age, Indoeuropean people migrated to Italy.
