History
Castillo de Argüeso, also known as the Castle of San Vicente, is a medieval fortification in Argüeso, Spain. Its foundation is placed in the late twelfth or thirteenth century, and its two principal towers were built in separate phases during the thirteenth and fourteenth centuries. The castle served both defensive and offensive purposes, while its position helped control seasonal livestock movement through the nearby Palomera mountain pass toward the Saja Valley.
Earlier religious site and medieval foundation
The hill was occupied before the castle by a ninth-century chapel dedicated to Saint Vincent and an early medieval burial ground dating from the ninth and tenth centuries. An archaeological intervention in 1989 confirmed that remains of the chapel survive beneath the medieval tower and in the arms courtyard. The chapel was later moved into the courtyard in the eighteenth century, while the necropolis remained the main surviving evidence of the earlier religious use of the site.
The date of the castle’s foundation is described as either the late twelfth century or the thirteenth century. A tradition attributes its construction to Alfonso XI, the fourteenth-century king of Castile and León. At an uncertain date, the king granted the castle to his son Tello Alfonso, a nobleman associated with the lordship of Aguilar and the title of Argüeso. Tello Alfonso later transferred it to his son Juan Téllez, whose marriage to Leonor de la Vega brought the lordships of Liébana and Castañeda into the family’s inheritance.
From the House of Vega to the Marquisate
The two towers initially belonged to the House of Vega, a powerful noble lineage. Through Leonor de la Vega’s second marriage to Diego Hurtado de Mendoza, they passed to the Mendoza family. In 1475, Diego Hurtado de Mendoza became the first Marquis of Argüeso, when Isabella I of Castile and Ferdinand II of Aragon, known as the Catholic Monarchs, transformed the lordship into a marquisate, a territorial lordship held by a marquis.
During this period, the fortification was enlarged and converted into a palace. A central body was added between the towers, together with a wall protecting the arms courtyard. Diego Hurtado de Mendoza’s children, Íñigo and Aldonza de Mendoza, later fought a territorial war that continued until 1576. After that conflict, the castle lost prominence, although it remained a center of the marquisate during the early modern period and subsequently served as the residence of the local mayor.
Private ownership and restoration
Mariano Téllez Girón, fifteenth Duke of the Infantado and fifteenth Marquis of Argüeso, sold the castle to private individuals in 1869. Its last private owner, Teresa Rábago García, donated it to the municipality of Campoo de Suso in 1962 on the condition that it be restored. The following year, the Ministry of Information and Tourism commissioned a feasibility study for converting the building into a small National Parador with eleven rooms. Directed by Jesús Valverde, the proposal was not implemented.
Restoration and rehabilitation began in 1988 and continued for approximately fifteen years. With financial support from the Regional Government of Cantabria, the work reconstructed the habitable spaces, of which only the exterior walls had survived. The intervention respected the original structure and retained selected remains for the study of the building’s archaeological layers. The castle was declared a Property of Cultural Interest in 1983 and later became a cultural center for the Campoo region, hosting temporary exhibitions and other cultural activities.
Remains
The castle has a polygonal plan and stands on a hill on the western side of Argüeso. Its surviving form is organized around two square towers joined by a lower central body, with a separate wall enclosing the arms courtyard. Stone construction, crenellated defenses, pointed-arch openings, and preserved archaeological remains combine to show the building’s development from medieval fortification to fifteenth-century palace.
Towers and central palace
Principal towers
The south tower dates from the thirteenth century, while the north tower dates from the fourteenth. Both are square, crenellated, and fitted with pointed-arch windows. Their construction is similar, but the north tower is turned differently from the south tower so that the two structures do not obstruct one another’s views.
Central body
A central body connects the towers and contains three floors that are lower than the tower levels. A further three-storey addition was incorporated into this central section during the fifteenth-century conversion of the fortress into a palace. Two access doors with pointed relieving arches open into the central body, while a separate pointed-arch entrance is set in the rear facade.
Defensive structures
Machicolations, which are projecting defensive structures with openings directed toward the ground below, reinforce the entrances. The gallery above the principal entrance was made of wood and formed a hoarding, allowing defenders to control the approach from above. Two stone machicolations project from the castle wall, one on the north and one on the south. Openings in the bases of these structures were designed to hinder enemy access. Crenellations protect the walls and towers, and the separate enclosing wall secures the arms courtyard.
Chapel and necropolis
Archaeological remains of the ninth-century chapel dedicated to Saint Vincent lie beneath the medieval tower and within the arms courtyard. The courtyard also contains a medieval necropolis with eight identified tombs and a ninth-century skeleton visible in place. These remains preserve the earlier religious and funerary use of the hill within the later fortified complex.
Restored interiors and surviving fabric
The restoration employed stone and traditionally worked wood prepared by local craftsmen under the direction of master builder Tomás Sobaler. The reconstructed interior was extensively fitted out in pine, including replicas of period tools and joinery made without nails. Mouldings in the halls, shutters, and steps form part of the interior treatment, while incised marks left by the master carpenter remain visible on the wooden strips.
Several physical remnants preserve material evidence of the earlier castle fabric. They include an original gargoyle, a millstone, and the only original piece of wood found beneath the rubble. Other selected remains were left visible within the restored spaces, where they continue to express the building’s archaeological layers and successive phases of construction.
