Dating from the late 12th century, it is one of the most prominent monuments in Valdepeñas, located in Plaza de España.

Its origins can be traced back to the late 12th and early 13th centuries, originally being part of the fortress of the Knights of Calatrava.
The facades feature sturdy buttresses and several doors. On the south facade, which faces Plaza de España, there is the “Puerta del Sol,” dated to the second half of the 15th century and dedicated to the Assumption, in the Isabelino Gothic-florid style, and the “Puerta de los Catecúmenos,” possibly of Romanesque origin, framed by a lintel that once held an image of the Piety. On the opposite side is the “Puerta de Umbría,” with a classical pediment flanked by two medallions of the Order of Calatrava, beneath which is a niche with an image of Saint Lawrence.

The tower, from the 16th century, consists of five sections and is topped with a slate spire, above which there is a ball and a cross.

Inside, the temple has two naves: the main nave, which houses the altarpiece attributed to Hernando de Yañez, of which the six original panels are preserved. This altarpiece has three sections, each with eight paired columns. Opposite the head, and above a pointed arch, is the choir with an organ dating from 1962.

The nave of Saint Lawrence is shorter and is separated from the main nave by arches from the 18th century. It has a small altar with panels of the four evangelists.

Another curiosity we can find inside is a small Mannerist chapel—penitential chapel—accessed through two gates decorated with the Calatrava cross, where we find tombstones and the triptych of the descent.

In the sacristy, we can admire the frescoes depicting the Calvary of Jesus Christ, with Dimas and Gestas on either side. On the upper floor, we have the parish archive from 1565.

During the restoration in 2018, burial niches from past centuries were uncovered, when it was customary to bury bodies in sacred ground beneath or adjacent to churches.
