The south side has outstretching turrets and a wide portico (the current main entrance) in Gothic-Catalan style, with three arcades, erected around 1465 and opening to the square. The first column on the left belonged to the original basilica and the subsequent mosque, as testified by the Qur'an verse carved on it. The carved portal of this entrance was executed in the period 1426 to 1430 by Antonio Gambara, while the magnificent wooden leaves are by Francesco Miranda (1432). The mosaic portraying the "Madonna" is from the 13th century, while the two monuments on the walls, works of the early 18th century, represents King Charles III of Bourbon and Victor Amadeus II of Sardinia, both of which were crowned here, the latter with his wife Anne Marie d'Orléans in December 1713.
