Called Monti Incappiddhatu in Gallurese dialect, the monumental Mushroom Rock is the symbol of the town. It is the most emblematic example among the tafoni. Since the Tertiary era, water, sun and wind have shaped the granite to its unusual shape. Ancient Neolithic people (3500 B.C.) immediately saw an ideal refuge in that huge boulder with the hat. With the other huts that gradually sprung up nearby, a small village was formed that was also inhabited in the Bronze Age (1500 B.C.) and until the Roman era, so much so that the settlement was given the name Turibulus Maior (large mushroom). Ceramic fragments, lithic tools, leftover meals, remnants of dairy processing, wool spinning, and plant fibers, as well as signs of waste dating from those periods were found in a nearby crevasse.
