The Prehistoric Rock Art Park in Grosio
The Rupe Magna stands at the center of the Prehistoric Rock Art Park [Parco delle Incisioni Rupestri] in Grosio: one of the biggest incised boulders of the Alpine mountain chain, it has more than 5000 markings that date back to between the fourth and first millennium B.C.. Human figures, animals and objects from everyday life are chiseled into the rock, along with geometric forms and holes.
Visits at sunset can be especially striking, as the horizontal rays highlight the incisions. The park, atop the Dosso dei Castelli, also comprises the ruins of two ancient castles besides the spectacular boulder: the Castello Vecchio di San Faustino (tenth-eleventh century), with its Romanesque bell tower, and the Castello Nuovo Visconteo (sixteenth century), encircled by a double row of walls.
Inside the Antiquarium located at the entrance to the park, in the Ca’ del Cap, visitors can see the relics found during two archeological digs carried out on the Dosso dei Castelli and the Dosso Giroldo.
