The cathedral has a history that dates to 1670. It has been damaged several times by fires and earthquakes. It stands out among Puerto Rico's other four cathedrals for its intricate design. It has a large pipe organ that was played by danza master and composer Juan Morel Campos. Architecturally, it is designed in the neoclassical style. Structurally, it follows a cruciform plan, with a large dome at the crossing. The interior consists of a main nave and two large aisles separated by a series of eight arcades. There are two small chapels in its interior. Two three-story square towers decorate the front facade.
