The Burnel is an ancient cup-marked stone located halfway along Via Maestra, the road that crosses the center of Nomaglio. On its surface, the cup marks engraved in prehistoric times are still visible, small hemispherical cavities whose exact function remains a subject of debate among scholars — perhaps linked to propitiatory rites or cult practices. In more recent times, the stone was adapted into a fountain, with a basin carved out for water, and on the stone, you can also observe the grooves left by the blades and knives that the villagers used to come here to sharpen. The name "burnel" indicates precisely this: a fountain with a stone basin. It is an object that, in a few square centimeters, tells of centuries of daily use superimposed on prehistoric traces, and has accompanied the life of the village for times much older than the stone houses with the typical Canavese arches that surround it.

Between the sanctuary of Oropa and the Rosazza refuge, at this point you can see a small but pretty waterfall of the Oropa stream. The water flows between several boulders to create a truly remarkable play of colors and reflections.

It is a "mica schistic monolith" that is, a single block of stone. It has large dimensions and a few tons of weight. We are not sure about its origin or function but it may have been used, in the Lombard era, as a burial place for a high-ranking person.
