The famous engravings rocks of Valle Camonica
The stone carvings of Valle Camonica constitute one of the largest collections of prehistoric petroglyphs in the world and were the first World Heritage recognized by the Unesco in Italy (1979). Unesco has recognized more than 140.000 figure, but new discoveries have progressively increased the total number of cataloged incisions, up to 200.000 if not 300.000. The petroglyphs are spread on all surface of the valley, but concentrated in the areas of Darfo Boario Terme, Capo di Ponte, Nadro, Cimbergo and Paspardo.The incisions were made over a time period of eight thousand years, until the Iron Age (I millennium BC), while the petroghyphs of the last period are attributed to the people of Camunni mentioned by Latin sources. The petroglyphs tradition does not end abruptly: engravings have been identified - although in very small number, not comparable with the great prehistoric activity - from the Roman period, medieval or even contemporary, until the nineteenth century. Most of the cuts have been made with the technique of "martellina", and lesser numbers obtained through graffiti.
