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, represent King Charles III of Bourbon and Victor Amadeus II of Sardinia, both of whom were crowned here (the latter with his first wife, Anne Marie d'Orléans, in December 1713). The area of the apse, enclosed by the turrets and grandly decorated on the external walls, is part of the original 12th-century building, while the more modern part of the church is the left side, which has an early 16th-century portal by Antonello Gagini. The South-Western façade, looking at the Archbishop Palace, dates from the 14th to 15th centuries. The interior has a Latin cross plan, with a nave and two aisles divided by pilasters. In the first two chapels of the right aisle are the tomb of emperors and royal figures moved here in the 18th century from their original sites (mostly from the basilica itself). Here are the remains of Emperor Henry VI, his son Frederick II, as well as those of Peter II of Sicily. A Roman sarcophagus is the tomb of Constance of Aragon, Frederick's wife. Under the mosaic baldachins are the tombs of Roger II, the first King of Sicily, and his daughter Constance. The last two were once located in the transept of the Cathedral of Cefalù. The Sacrament chapel, at the end of the left aisles, is decorated with precious stones and lapislazuli. To the right, in the presbytery, is the chapel of Saint Rosalia, patron of Palermo, closed by a richly ornamental bronze gate, with relics and a 17th-century silver urn which is object of particular devotion. The 1466 Gothic-Catalan style wooden choir and the marble remains of the Gagini's retable (removed during the 18th-century alterations) are also precious, as well as a marble statue of the Madonna with Child by Francesco Laurana and pupils (1469), a 13th-century polychrome Crucifix by Manfredi Chiaramonte, the holy water stoup on the fourth pilaster (by Domenico Gagini) and the Madonna della Scala by Antonello Gagini, on the high altar of the new sacristy. The Relics Chapel contains the relics of St. Christina, St. Ninfa, St. Cosma, St. Agatha and St. Mamilianus, first patron of Palermo. The crypt, accessed from the left side, is an
