Well-kept and surrounded by a low wall that separates it from the other buildings in the village, the parish church of Nuestra Señora de las Candelas presides the main access road to the village of Martes and gives it a special character.

Martes parish church is a stone building resulting from the extension of an original Gothic church in the first half of the 16th century, which was in turn modified in the 17th century. It has one main nave and another shorter and narrower nave on the Gospel or left side, which extends through the sacristy and is closed off by a right-angled wall. Both the portico which gives access to the sacristy and the lateral Gospel portico bear late-Romanesque medieval features such as pointed arches and delicate floral ornaments. Likewise, the two star-ribbed vaulted ceilings are witness to the extension work carried out in the 16th century. The remaining vaults have been substituted by barrel vaults with lunettes and supporting arches which end in prominent corbels. The 16th and 18th century altarpieces are of unusully good quality, particularly the main altarpiece dedicate to the Virgin Mary - an impressive example of the Gothic style in transition to the Renaissance.

The main doorway is in Gothic style with diminishing arches and floral motifs on the frontispiece. Above the doorway is the symbol of the Monastery of San Juan de la Peña, the Agnus Dei (Lamb of God) wearing a crown. Three other chapels can be found in the surrounding area. These are the chapel of St Pelay, the chapel of St Sebastian and the chapel of Nuestra Señora de Javierremartes (belonging to the “Pardina del Solano” estate), of Romanesque style (late 12th century) and originally the parish church of the village of the same name.
