The original church was built between the 15th and 16th centuries. Located near the Camino Real de la Plata and behind the missing Castle, it was the only parish in Malagón until 1962, the year in which a new parish was erected with the name of Santa Teresa de Jesús. The current church preserves its original layout: three-nave floor plan, apse and central pilasters. The dome that tops the transept has been replaced by a modern lantern that illuminates the transept and the presbytery.
