Officially known as Piazza Vigliena, Quattro Canti is considered one of the most fascinating landmarks of Palermo. Located at the intersection of Via Maqueda and Corso Vittorio Emanuele, it has an octagonal structure shaped by the elegant facades of the buildings standing at its corners. During the day, the sun is always shining on at least one of the four facades: leading to this Baroque gem being nicknamed by locals "il teatro del sole" ("the theatre of the sun").
