The intersection of Emmanuel Avenue and Marka Street is a small circular square, which is known as the Four Songs Square, also known as the Four Corner Square. Here is the landmark of Palermo and the city center. The four corners of the central street are curved, and if you look down from the sky, it is a circle. The baroque sculptures of the four building facades are all symmetrical. Each building has three floors. From bottom to top are the fountain sculptures representing the four seasons, the four Spanish kings of Sicily and the four guardians of Palermo. Look at the corners of the square are people, the stools, the chairs are full of people, even the edge of the flower bed is filled with people, here, nothing, sit For those outside the city, it may be to look at novelty, and as the citizens of this city, it is more to come to the cold, or actively participate in the cultural life of this square.

Via Maqueda

Via Maqueda, along with Via Vittorio Emanuele, one end of Via Maqueda is the Politeama Theatre, and the other end is the central railway station; one end of Via Vittorio Emanuele is the Norman Palace and the cathedral. Quattro Canti, built between 1608 and 1620, is surrounded by four inwardly curved arc buildings forming an octagonal (almost circular) square. This structure makes it an excellent open-air opera house, hence Quattro Canti is also called Teatro del Sole - Sun Theatre. Street performers perform here almost every day, with excellent sound effects.
