The Nuestra Señora de la Antigua Church, built in the Mudejar style, underwent extensive renovation during the 18th and 19th centuries. The church is accessed through a semi-circular portal. To the left of this portal is a tile panel of Our Lady of Antigua, to whom the church is dedicated. Crowning the entrance is a bell gable containing two bells. The church has a central nave and two aisles separated by rows of pillars with a square base, covered by a wooden ceiling.
The main feature in the Sanctuary is the wood altarpiece painted with a speckled effect and finished with some gilding. The altar is presided over by a 16th-century image of the Christ of Sorrows. A large painting of the Pietà hangs on the right wall, and on the opposite wall is an image of Our Lady of Antigua, one of the town’s patron saints, who is holding the Child Jesus. The Tabernacle Chapel is in the chancel of the right-hand aisle. Its altarpiece contains a 19th-century image of the Child Jesus as the Good Shepherd, by Juan de Astorga, as well as two 18th-century angels holding lamps. A carved wooden statue of Saint Teresa of Avila from the mid-17th century is also in this aisle.
This parish church is home to a 17th-century sculpture of Saint Didacus of Alcalá, the other patron saint, during part of the year. The standard of the Confraternity of El Rocío is also worshiped at one of the church’s altars.
