Length: 84 mts; Width: 35 mts; with more than 5000 engraved figures, datable between the end of the Neolithic (IV millennium B.C.) and the Iron Age (I millennium B.C.). This is the "Identity card" of the "Rupe Magna", one of the biggest engraved rocks in the Alpine range. Numerous themes are represented: antropomorphic figures (praying and armed), animals, geometric shapes, cup - marks (so - called "coppelle") and objects from everyday life. Some crosses, symbols of the Christian religion, witness the tradition of rock engraving even in the historic age.
