Valcamonica is famous for its rock carvings. Located in Lombardy, it extends about 90 km in the middle of the eastern Alps, between the provinces of Brescia and Bergamo. The valley takes its name from the Camuni, inhabitants of that area during the Iron Age (I millennium BC). The more than 250,000 rock carvings make the valley rich of petroglyphs as to be considered the biggest in the world. All the engravings on over 2500 rocks were made in the course of eight thousand years and tell the evolution of the uses and customs of our prehistoric ancestors. The oldest petroglyphs, such as those found in the municipality of Darfo Boario Terme, depict large animals. The carvings of human figures and geometric elements of the Neolithic such as those of the Regional Reserve of Ceto, Cimbergo and Paspardo instead testify the spread of the first agricultural practices. Appear at this time also the first representations of religious nature. It harks back to the Copper Age the realization of boulders stained with human beings and symbols related to the appearance of the wheel and raw metal processing techniques.
