Originally this was a humble monastery, but after 1700 it was converted into an opulent work of baroque architecture, whose atrium included what is now San Antonio Plaza (square).

The church still has simple stone facade, two sectioned tower and square base.

Inside, once richly decorated with baroque alter pieces, now has neoclassical alters, the remains of an organ and some paintings as sculptures.

The small simple cloister is very original and the first floor breezeway there are Talavera tiled panels 15 showing the Via Crucis.
