Santuario di Santa Rosalia

"Mount Pellegrino, which towers over the coast between Palermo and the beach of Mondello, is a popular day excursion from Palermo. The panoramic view from the top is breathtaking. And while you're up there you can visit the sanctuary of Santa Rosalia, who is believed to have saved Palermo from a plague in the 1600s. She lived in a cave on the mountain until her death around 1160, and more than four centuries later hunters found remains that were thought to be hers. The plague in Palermo ended, it was believed, because her bones were finally given a proper Christian burial. This shrine was built around her cave to protect the site, and Santa Rosalia was named the patron saint of Palermo."
