The sanctuary is in a beechwood at 919 m altitude in the Camandona municipality.[2]
The building has one aisle and a small belltower and was built in 1662. In the 18th century a portico was added to the façade, above which a hermit lived. The structure was modified during the 19th and 20th centuries.
The main altarpiece is a canvas depicting Saint Anne by Carlo Sogno (1900); the other paintings were made by local artists. The façade was frescoed in 1988 with a representation of the Virgin Mary and baby Jesus.
Since its foundation this small sanctuary was inhabited by hermits, from the mid-1700s to 1901, when the last hermit died.
The area is surrounded by beeches. In front of the sanctuary there is a fountain, like in all the others sanctuaries of the Biellese territory.
