Espinosa de los Monteros

People have lived around Espinosa de los Monteros since deep prehistory. The archaeological site of Ojo Guareña and remains from the Bronze Age and Iron Age confirm long settlement before any written record. In the medieval and early modern periods the town was royal jurisdiction, part of the district of Castilla la Vieja in Laredo, and administered as a villa with six surrounding barrios.

The end of the old regime brought constitutional reorganisation, and Espinosa was folded into the partido of Villarcayo, still with its six barrios intact.

The sharpest moment in the town's modern history came in November 1808, during the Peninsular War. On the 10th and 11th of that month, Spanish forces were defeated by Napoleon's army in a battle fought at Espinosa. The French victory was followed by looting, arson, and violence against the civilian population — damage the town carried for years afterwards.

By the mid-nineteenth century Espinosa had recovered enough to count around 2,000 inhabitants, and it earned an entry in Pascual Madoz's monumental geographical and statistical dictionary of Spain, one of the key reference works of the period.

Within the province of Burgos, Espinosa de los Monteros has more officially catalogued monuments than any town except the capital itself. Centuries of prosperity left behind a dense collection of towers, palaces, and fortified houses.

The most prominent military structure is the Torre Ilustre, also called the Torre de los Velasco. A Gothic defensive tower of considerable size, it stands on a rise beside the river Trueba. Its walls are dressed stone laid in regular courses, and five shields of the Velasco family — among the oldest in the comarca — are carved into the façade. It probably dates from the fifteenth century, with later additions.

The Torre Berrueza is a two-storey tower from the sixteenth century, originally defensive. Small openings in the upper floor were once used by carrier pigeons. It has since been converted into a hotel.

The Palacio de los Fernández-Villa, also known as the Palacio de Carrillo del Hoyo, is a Renaissance palace begun in the mid-sixteenth century, built against an earlier fortified house. Its most carefully worked element is the western tower, where a flat-topped doorway flanked by fluted columns on a high podium opens onto the interior courtyard. It was declared a monument of cultural interest in March 2000.

The Torre de los Azulejos, on the Calle de los Monteros, takes its name from the decorative tiles set into its windows. A Renaissance structure with a square plan, thick ashlar walls, and a simple semicircular entrance arch, it follows the classic fortified-house form.

The Palacio de Chiloeches, on the Plaza de Sancho García, was commissioned by the Marqués de la Gandara Real in 1600. Two large towers with small pinnacles frame its façade, Renaissance in origin but with baroque details in execution. Napoleon's troops used it as a barracks after the 1808 battle and burned it on their way out. It was declared a monument of cultural interest in June 1991.

The Plaza de Sancho García is the town's main square and civic centre, home to the ayuntamiento and the site of markets and festivals. Around it stand examples of the local vernacular house type — the casa montañesa, with strong Cantabrian influence, typically featuring either a long wooden balcony hung with flowers or enclosed glazed galleries.
