Built in 1343 with the annex convent, this church was used by the Angevin dynasty to bury their last family members. It is one of Naples's hidden gems and is likely to stay that way considering that it's rather hard to find. The church stands at the top of a sweeping double stone staircase; at the top of the stairs is the chapel of Santa Monica (closed to the public) with a marble gothic portal; the entrance to the church is on the left of this portal. Inside are several important works of art, including, over the high altar, the towering Monumental Tomb of King Ladislao, a 15th-century masterpiece by several Tuscan artists. Behind the monument is the circular Cappella Caracciolo del Sole, with a rare majolica floor and beautiful frescoes from the 15th century. To the left of the high alter is another round Caracciolo family chapel, the early-16th-century Cappella Caracciolo di Vico, built entirely of marble and graced by a beautifully carved 16th-century altar. At the end of the courtyard, an entrance gives access to yet another chapel: the Cappella Seripando, with a Crucifiction by Vasari.
