It is a single-nave building with diaphragm arches and a wooden ceiling, made of masonry and ashlar. Looking at the altar, its right wall is supported by the remains of the first medieval town wall from which it is possible to see its entrance door. On the outside, we can observe remains of a tower which is part of the current sacristy.
At the beginning of the 18th century, the façade, tower, choir and a Baroque covering were added on the church. The latter was of poor-quality and was removed during its restoration in 2003 and 2004.
Inside the church, it is important to highlight the stone medieval altarpiece dedicated to St. Peter and St. Paul (14th century), which was found fragmented around the nave during the removal work of the Baroque frame.
