It is one of the oldest churches in the city, in Romanesque style, with ornamental elements from the 13th century. Mudejar and Romanesque details can be seen. Both the exterior and the interior of the apse have been saved from transformations, with a large semi-cylindrical apsidal drum with a brick impost and window with corbels, some of which date back to the 15th century.
The tower contains a first body of stone and then another of brick, in which the windows open on each of its four sides. The top of the tower is a hemispherical dome, above which is a weather vane. The tower is close to the old city wall.
The bells were used to call the patron saint festivities of the old guilds of market gardeners, wine harvesters and olive growers, which were held in the Plaza de San Pedro. Mudejar decorative elements remain in the square. Near the square, there is a dry fountain with the name of the parish church.
Inside, it has a single nave, with the typical choir of rural churches, and a pointed triumphal arch at the chancel, with a pointed half-barrelled presbytery section and an apse with an oven vault. On the side there is a Romanesque doorway with semicircular archivolts. The most important image is the crucifix that presides over the main altar, a late Romanesque work from the 14th century. The altarpiece is from the 17th century, next to the baptismal font, on which there is an inscription:
“CHAPEL | CHAPLAINCIES | ORNAMENTS IS OF FRANCISCO DE LA CALLEJA | OF HIS BLACKSMITHS | THIS ENDOWED WITH PATRONAGE YEAR 1605 YEARS SAINT MARTIAL”.
The four main panels represent: The Annunciation; The Birth; Crucifixion and Resurrection. Two central images: Saint Martial and the Assumption of Mary. On the plinths there are two scenes of saints. In the intercolumniations four martyrs: Saint Agnes, Saint Lucy, Saint Catherine and Saint Beatrice. On the left side, on a small niche, is San Gregorio from the 14th century, patron saint of the market gardeners, as it is the closest to their orchards in Jerte. The bell tower is very interesting.
Anything to improve?
