 In 1191 , the king confirmed the monastery and its surrounding fields as belonging to the Cistercian Order . The aged abbot of Santa María de Huerta , bishop Martín de Finojosa ( later canonized ) , consecrated the church in September 1213 and died days later . The surrounding area of Murel and Trillo along the Tagus prospered , giving tithes and gifts of land to the monastery . The cartulary , Cartulario de Óvila is preserved at the University of Madrid .
