It provides access to a number of important sights, including the Royal Palace (also known as Palazzo dei Normanni) and the Cathedral, two UNESCO World Heritage Sites.

Via Maqueda, also known as "Strada Nuova" (New Street), is an important street of Palermo. Together with the Cassaro, it represents the main axis of the historic centre and provides access to a number of important sights, including Teatro Massimo and Fontana Pretoria. The street is named after the Viceroy of Sicily Bernardino de Cárdenas y Portugal, Duque de Maqueda.

The Charles V Monument is a monumental sculpture erected in 1631 on Piazza Bologni in Palermo, Sicily. It was initially designed to be placed in the center of the Quattro Canti but was eventually erected in its current location. The statue of Charles V was created by Scipione Li Volsi of the Li Volsi family of Sicilian sculptors. It portrays him as a triumphant Roman Emperor, with reference to his months-long stop in Sicily (including Palermo) following the Conquest of Tunis (1535). The marble pedestal is by Giacomo Cirasolo and Luigi Geraci with sculptures by Giovanni Tagliavia. The Latin inscriptions praise Charles and compare him to "the brothers Robert [Guiscard] and Roger [first Count of Sicily]", who had brought an end to Muslim rule in Palermo in January 1072.

It is located in the main street of the city, the ancient Cassaro now Corso Vittorio Emanuele, in the quarter of the Loggia, about a block east of the Quattro Canti, within the historic centre of Palermo. The church was built between 1633 and 1664 by the will of the Miseremini confraternity, dedicated to prayers for souls in Purgatory. The building was probably designed by the architect of the Senate of Palermo, Mariano Smiriglio, but was completed by Gaspare Guercio and Carlo D'Aprile. It is decorated with many works of important Sicilian artists like Vito D'Anna, Pietro Novelli, Giacomo Serpotta, Giuseppe Testa (painter), Bartolomeo Sanseverino, Filippo Randazzo, Antonio Manno, Francesco Sozzi.
