On one of the offshoots of Mount Saint Martino (850 mt), above the village of Campi, you can find the Saint Martino archaeological site. The most important finding consists of the ruins of a large building, most likely a sanctuary where female divinities were worshipped, constructed on the remains where former cult rituals used to take place. Despite the location’s age, set between the second to fourth centuries after Christ, the frequency of religious visits to the mountain, after the Romans, extended well into the Middle Ages. The findings of this area are preserved in Museum of Riva; some copies can be visit in the Centro di Documentazione di Pranzo di Tenno.
