Built on fragments of old walls, this church is located in the centre of the town’s historic quarter. It has a Gothic design with added Renaissance and Baroque touches. It was built with elements used from the fifteenth to the eighteenth century. The sacristy was built on the medieval wall in the first half of the seventeenth century. The eighteenth century Baroque belfry, built on a previous tower house, is a work of Francisco de Ibero.The temple’s ground plan has a Latin cross shape, with three naves at different levels. The star-shaped vault under the choir stall that is supported by a highly decorative low arch is outstanding, where the varied religious and heraldic iconography is striking. The picture of the Trinity as a figure with three heads merged together holding an equilateral triangle in his hands attracts attention. According to some specialists, this is the only picture of this type that has survived in the Iberian Peninsula and is probably one of the very few that exists in Europe.The church has two entrances from the outside. The main one is from the Mayor (Main) street. This main entrance, the construction of which was contracted in 1566, offers a hybrid appearance between a Gothic and Renaissance style. A large decorated arch with casetones frames the entrance literally divided into two parts by a mullion on which a classicistic boarding is placed, crowned by a kind of pediment with the image of the Virgin of the Assumption standing out in the centre.
