Church of Santa María de Dueñas Monument · Dueñas, El Cerrato, Palencia The church of Santa María de la Asunción, the main church of Dueñas (Palencia), forms part of the historic-artistic ensemble of the town centre, a title it has held since 1967. Construction began in the late 12th century in a style transitional between Romanesque and Gothic, a late Romanesque of Cistercian tradition; it is dedicated to the Assumption of Mary, a feast celebrated on 15 August. Inside it holds carvings by artists such as Gregorio Fernández and Diego de Siloé, a Hispano-Flemish main altarpiece, choir stalls and the pantheon of the counts of Buendía. Here, in 1474, the Order of the Golden Fleece was conferred on Fernando de Aragón, who had resided at the palace of the counts of Buendía before marrying Isabel.
