This Catalan Gothic cathedral stands in the old town overlooking the ocean. Begun during the reign of Jaume II (1276–1311), it was completed in 1601. Its central vault is 43m (141 ft.) high, and its columns rise 20m (66 ft.). There is a wrought-iron baldachin (canopy) by Gaudí over the main altar. The treasury contains pieces said to be part of the True Cross, and relics of San Sebastián, patron saint of Palma. Museum and cathedral hours often change, so call ahead.
