It was a primitive cell, property of the monastery of Sant Medir and Sant Genís, near Girona. This cell gained importance when, a century later, the monastery of Sant Medir was destroyed by the Hungarian invasions, and the community moved to the Amer valley.The consecration of the church took place in 949.
