It is located at number 25 Doctor Tortosa Street, in the heart of Alarcón, Cuenca, where it dominates the whole village. It is a temple of large dimensions, built in the sixteenth century with ashlar masonry and can be considered Renaissance style for its buttresses, lintels, doors and windows. However, the Monumental Catalog of the Diocese of Cuenca refers to it as Plateresque style. It is a transitional work, showing the transition from Gothic to fully Renaissance forms.

It is a columnar church with a hall plan and three naves with ribbed vaults that start immediately from the shafts of the columns, since these lack capitals. The ribs of the vaults of the central nave create radiating stars, while the ribs and ornamentation of the side naves are simpler. It has a five-sided polygonal apse and two columns curiously ornamented with a large shell motif that connects to the Order of Santiago at the point where the base and shaft of the column meet. A prominent altarpiece in this apse, which dates from approximately 1572 and is where the main altar is located, features some noteworthy carvings. On both sides are the chapel and the sacristy. The chapel has a square floor plan, a half-orange dome on pendentives and a wooden door that closes it. The sacristy also has a square floor plan with plasterwork of biblical scenes from the 18th century. A starred vault with medallions in the joints of the ribs covers the central space of the front, before the presbytery. Along the flanks, there are shallow chapels with tierceron vaults covering them. At the base of the church is the choir.

The main entrance to the church is on the south side. The portico is covered by a massive triumphal arch on the exterior. This semicircular arch juts out from the façade and rises to the height of the cornice of the building. It is adorned with coffers in the soffit and a double fluted colonnade on an ashlar plinth on each side. The church is accessed through a door with a semicircular arched doorway, voussoirs and two pairs of Corinthian columns, separated by two levels of niches with niches for shells. On the dividing impost of the second part, corbels support a profusely ornamented railing. Above it are three niches; the lateral ones are smaller, and a pediment with roundels and acroteria tops the whole structure.

The north door is flared, with a segmental arch divided into quadrangular cards and round mirrors in the spandrels. It also has a pediment, metopes and a triglyph frieze. On the west side of the church is a modest door with a semicircular opening and four attached ribbed archivolts. Pedro de Alviz designed the church, while Esteban Jamete designed the south doorway.

By decree published on March 4 of the same year in the Official Gazette of Castilla-La Mancha, it was declared an Asset of Cultural Interest in the monument category on February 19, 1992.
