The church, whose present appearance is due mainly to the reconstruction done during the 16th century, but still containing remnants of the first church, from the 15th-16th centuries, on the chancel and the choir section.
This first church had a rectangular floor plan and no transept.
The present temple is in the form of a Greek cross with an octagonal chancel covered by stellar vaults. The sacristy is also covered by this type of vault.
The doorway consists of a rounded arch decorated with geometric motifs on two moulded capitals. The double altar superposed with a decorated recessed arch is noteworthy.

The 16th-17th century tower features spans with rounded arches. There are a set of 16th century images on the lower part of the main altar, somewhat moth-eaten, and a post-medieval undecorated font.
