The town was the manor of the Counts of Siruela and fell on one of the Roman roads towards the Cantabrian Sea, which is why it preserves houses emblazoned with coats of arms, squares and numerous monuments, the vestiges of its historic past. Prominent in the town are the square, embellished with stone columns from the 16th and 17th centuries; and the church of Santa María del Castillo, a Gothic work from the 16th century which has been declared a National Monument, outstanding in which is the funeral chapel of Santa Ana, with its Hispano-Flemish reredos featuring a panel by Juan de Flandes, La Adoración de los Reyes. On the outskirts of town is the hermitage of San Vicente and at a distance of three kilometres, the Fuentes Carrionas Parador Nacional hotel, which sits in a landscape dotted with mountain lakes and enormous peaks.
