Opposite the bay, in a cave where the Saint took refuge in 1221 during a storm, this sanctuary was set up on the initiative of a noble, Andrea Guerrera. In the 18C, it had altars added and dressings of multicoloured marble and low-reliefs in stucco.

This square is named after a grain store ( peculio frumentario) where the locals could buy wheat for a modest sum. The arch that you will see on the terrace of the belvedere, behind the Pawnbroker's, is believed to have come from what was most likely the Jewish area of Castroreale. As for the Church of Santissimo Salvatore, it still awaits restoration after an earthquake in 1978, which caused a section of its campanile to collapse.

Set up in the ancient oratory of St-Philippe Neri, this museum unites wood paintings and marble sculptures. Amongst these pieces there is a marvellous funerary monument of Geronimo Rosso, by Antonello Gagini. Paintings worth mentioning are the Savoir of the world, as envisioned by Polidoro da Caravaggio, which was heavily influenced by Raphael and the beautiful Virgin and Child by Antonello de Saliba.

This is bordered by the Palace of the Viceroys, built in the 16C and embellished two centuries later with balconies and Baroque consoles and by the church of Santissimo Salvatore, whose 18C facade is by Giovan Battista Vaccarini.
