It was built between the late 12th and early 13th centuries by Commander Fernán (Hernán) Rodríguez de Valbuena, becoming a funerary chapel for the Order. For centuries, it served as a fortified church overlooking the Duero River, and was linked to the now-vanished castle and other medieval chapels in the town. It suffered several collapses in the 19th and 20th centuries, until the original ruins had practically disappeared; the current structure is the one dedicated to Santa María del Castillo (Saint Mary of the Castle).
