In August, for more than 300 years a group of faithful of the Sanctuary hold a Feast with the departure of the procession at 3.00 am.
The sanctuary is located in the Abruzzo National Park, at 1020 meters above sea level, and was established where the Virgin Mary appeared to a young shepherdess. Madonna also made a source of water gush out that becomes part of the Melfa River. Here were also found traces of a pagan temple dedicated to the goddess Mefiti V-IV century BC.
Pilgrims come from all over Lazio, Campania, Abruzzo and Molise, giving rise to the Feast of the Four Regions.
