There’s a reason this church's ashlar diamond projections facade looks nothing like a church. Built in 1470 for Roberto Sanseverino, the Prince of Salerno, the church used to be a palace until it was sold to the Jesuits in the 1580s. There’s been a lot of conspiracy talk about the meaning of the symbols that decorate the diamonds - these were later found to be archaic Aramaic musical notations. The decoration inside the church is so dense it’s a little over the top - but still beautiful. The frescoes inside are lovely, especially the Expulsion of Heliodorus from the Temple, which is thought to be a masterpiece. Other highlights include the three bronze bas reliefs near the altar, the busts of eight saints above the altar, and seven ornate chapels of various significance. Napoli Saint Giuseppe Moscati is interred here.
