The Park of rock engravings is a journey that accompanies visitors in the most uncontaminated nature and in the most ancient history. The Rupe Magna is the largest alpine rock that has ever been carved by man and houses more than 5,000 incisions placed chronologically between the end of the Neolithic and the Iron Age. The great variety of the themes represented indicates how the Valtellina daily protohistoric life could be carried out. The practice of engraving the rock also remains in historical age, two crosses are evident evidence of Christian religiosity. The findings associated with the various protohistoric phases show the presence of very peculiar cultural aspects, characterized by alternate relationships now with the transalpine area of the upper Rhine valley (Grisons), now with the south-eastern area of the central-eastern Alps (Trentino -South Tyrol).
