The Sanctuary of Santa Rosalia is a church and pilgrimage site located on via Bonnaojust outside of the urban neighborhoods of Palermo, nestled against a stone cliff wall on Mount Pellegrino, which looms to the north of the Sicily city. On 15 July 1624, putative relics of this 12th century saint were discovered in a cave at the site, and since the plague ebbed after these bones were paraded through town, Saint Rosalia was adopted as the fourth female patron saint of Palermo, and this sanctuary was erected in her honor.
