The temple, with a rectangular layout and three naves, is a testament to the stylistic richness of the era, merging Baroque and Neoclassical elements. The main facade stands out for its elaborate Baroque doorway, designed by the renowned architect Antonio de Figueroa y Ruiz, featuring stone ornamentation with a mixed-line design that emulates the exuberant style of Sevillian Baroque. This doorway is flanked by attached columns and topped with a projecting cornice that encloses a papal coat of arms.
Inside, the church is structured into three naves separated by rectangular pillars and semicircular arches. The central nave, wider and taller, is covered with a barrel vault reinforced with transverse arches, while the side naves are topped with groin vaults. The presbytery, consisting of two rectangular spaces, features a segmented dome with ribs and a red marble surround, offering an impressive view from the outside.
The chapels attached to the Gospel nave and the sacristy, which has a square plan, add significant historical and architectural value to the complex. Notable are the chapel of the Immaculate, with its hemispherical vault and exuberant decoration, and the chapel of the Sacred Heart of Jesus, which presents a vaulted design with cherubs and floral motifs.
The four-part tower combines ashlars and brick, with an elegant topping of cobalt blue glazed ceramics. The structure includes bells, a clock, and an octagonal spire with glazed tiles, adding a distinctive touch to the building
