The refuge was built on the site of a chapel built in 1656, alongside a consecrated spring which has been the destination for pilgrimmages for centuries.
First of all a barn and then a refuge for pilgrims, it has been opening its doors to travellers who appreciate the basin with its mountain pasture at the foot of the Becca del Merlo and its closeness to the lakes of Cuney, Becca Fontaney and Monte Morion since long ago.

Free overnight stay for coach drivers and holiday representatives who are providing assistance to groups of at least 25 persons, organised by travel and tourist agencies
