The main façade is made of plastered masonry, with cornerstones topped by pyramidal pinnacles, a straight portal topped by a cornice and a triangular pediment with a niche.
The main body is divided in two by an arch whose intrados is painted with floral motifs, and on the left-hand side sits the pulpit. The ceiling is painted in two different parts, the first showing St. Martin in the center, as bishop of Tours, and the second, more decorated, showing God in Majesty in the center, and the four Evangelists on the sides.
On the sides, the altarpiece of the Passion, in gilded woodcarving, with the painting of Our Lady, St. John and God the Father, and on the inside of the arch, paintings of the objects of the Passion. The altarpiece of the souls in purgatory, dating from the 17th century, is unique in the municipality as it features St. Francis and St. Dominic on the sides and St. Lawrence in the attic.
The chancel is decorated on the sides and ceiling with coffered ceilings depicting saints, apostles, the life of the Virgin, Christ and Saint Barbara.
