The Buco del Piombo offers a unique experience for lovers of nature and history. Explore nearly 300 meters of galleries where important paleontological remains of Ursus spelaeus have been discovered, along with flints and tools dating back to the Paleolithic era, left by ancient nomadic hunters.

The masonry structures inside the entrance hall are of considerable archaeological interest, dating back to around the year 500. The cave served as a strategic refuge during invasions and historical conflicts. According to local legends, in 1160 the warriors of Erba took shelter here after their victory in the Battle of Carcano against Barbarossa. In 1316, the noble knight Guelfo Parravicini chose this cave to draft his will.
