Piedra Santa is a large rock outcrop near Malalcahuello in Araucanía Region, Chile.
It is best known for folklore and folk catholicism associated to it.
Piedra Santa is said to be a Mapuche princess, and the daughter of great warrior, turned into rock.
[1] People who travell between Curacautín and Lonquimay stop at Piedra Santa to deposit food and other gifts in order to "feed" the princess.
