Discover prehistory in Valtellina. Where? Between the municipalities of Grosio and Grosotto, in the Parco delle Incisioni Rupestri (Rock Engraving Park). This is where the ancient populations left signs of their presence, engraving pictures into the rock that represent their daily life, covering a period of time that went from the late Neolithic to the Iron Age. Warriors, anthropomorphic figures and animals cover the surface of the spectacular “Rupe Magna”, one of the biggest engraved rocks in the Alpine mountain range. Arrange a visit at sunset, when the angle of the light makes it easier to see the engravings. Book a guided exploration of the Rupe Magna and the castles of San Faustino and Visconteo.
