In the 18th century a fire destroyed virtually the entire nave volume, with only the apse, tower, wood choir and the altarpiece dedicated to the church’s patron saint, done by Bartolomé de Bermejo, left standing. At that time, the decision was made to create a new nave volume in the Baroque style. The orientation was shifted so that the church would face west-east, leaving the former polygonal apse and Mudejar tower at the west end of the new building.

The exterior is divided into two parts as a result of the change in building materials, with the bottom part constructed of ashlars and the upper section made of brick. The upper section features openings separated in the middle by a cylindrical column that acts as the springing line for mixtilinear arches. These arches are framed and finished by two trilobed arches, with a secondary frame consisting of a lintel with bricks arranged vertically. Finally, there is a second level of openings featuring round arches on which another double arch rests.

The tower dates from the mid-13th century. It is a square-plan structure initially constructed using ashlars, and the interior houses a spiral staircase. The second phase of the tower was built of brick, leaving the interior hollow. The interior is divided into two rooms covered by rib vaults with round diagonal arches. These two rooms are connected by a spiral staircase located in a corner of the tower.
