The Chiesa di San Cataldo is a church of the Sicilian city of Palermo, on the central Piazza Bellini. It is a notable example of the Arabian - Norman architecture which flourished in Sicily under the Norman domination of the island. The church is annexed to that of Santa Maria dell'Ammiraglio. Founded around 1160 by admiral Majone di Bari, in the 18th century the church was used as a post office. In the 19th century it was restored and brought back to a form more similar to the original Mediaeval edifice.
