The Santuario della Madonna dell'Arco is a Roman Catholic shrine in Sant'Anastasia, a town on Mount Vesuvius. Every Easter Monday, it is the destination for the traditional 'fujenti' or 'battenti' pilgrims from all over Campania, who sing a song first written in the 15th century and later put to music. A fire is also lit on the bell-tower every second Sunday in September for the feast of the Coronation of the Virgin.
