The Quattro Canti is a spectacular example of Sicilian Baroque architecture on a grand scale!  Marking the entrance to Palermo's historic district, the Quattro Canti (technically Piazza Vigliena) is a large octagonal piazza laid out in the early 17th century, four side of which are occupied by Baroque facades. Each of these facades contains allegorical fountains on the ground level, statues of Sicily's Spanish rulers of Sicily on the next, and Palermo's four patron saints above.
