Today’s visitors to Greece have the opportunity to trace the “fingerprints” of Greek history from the Paleolithic Era to the Roman Period in the hundreds of archaeological sites, as well as in the archaeological museums and collections that are scattered throughout the country. The first traces of human habitation in Greece appeared during the Paleolithic Age (approx. 120000 - 10000 B.C.). During the Neolithic Age that followed (approx. 7000 - 3000 B.C.), a plethora of Neolithic buildings spread throughout the country. Buildings and cemeteries have been discovered in Thessaly (Sesklo, Dimini), Macedonia, the Peloponnese, etc. The beginning of the Bronze Age (approx. 3000-1100 B.C.) is marked by the appearance of the first urban centers in the Aegean region (Poliochni on Limnos). Flourishing settlements were found on Crete, Mainland Greece, the Cyclades and the Northeastern Aegean, regions where characteristic cultural patterns developed.
