Just off the southeast corner of the Plaza de Armas, this Jesuit church, one of the oldest in Arequipa, is noted for its ornate main facade and main altar, which is carved in the churrigueresque style (an intricate decorative motif popular during the late Spanish baroque period) and completely covered in gold leaf. To the left of the altar is the San Ignacio chapel, with a polychrome cupola smothered in junglelike murals of tropical flowers, fruit and birds, among which mingle warriors and angels.
