San Parteu is one of the mountain peaks of Balagne. It rises to an altitude of nearly 1680m between the Melaghja Valley and the Fiumi di Regino Valley. It dominates Feliceto on its north-western side and Pioggiola on the north-eastern side. It borders the north-western part of the Corsican Regional Natural Park. It is the subject of a procession in July in memory of the saint who is said to have blessed the Balagne in the 5th century. The San parteu also gave its name to the brotherhood of Ghjunsani.
