Situated on the Argimon mountain, 450 metres above sea level, the present-day sanctuary dates back to the 18th century. It is a modern structure located on the site of the ancient Argimon castle, *“Castro Argimonte”*. The ruins of this ancient building are the remnants of a square, eight-metre-high tower, which must have had three floors, and the primitive Romanesque chapel dating back to the 11th century.
Argimon Castle is documented as early as 925 and was part of the domain of the Viscounts of Cabrera in the mid-11th century. From the 12th century, it was a fully functional castle with jurisdiction over the parishes of Riudarenes, Vallcanera, Castanyet, l’Esparra, and Sant Pere Cercada.
