Castrojeriz

Castrojeriz likely traces back to the ancient Castrum Sigerici mentioned in 9th-century chronicles, with documented linguistic evolution to its current name. The hilltop castle ruins mark the town's original settlement, founded by Count Muño Núñez who defended it against Arab forces in the late period. The site had previously served as a Celtiberian, Roman, and Visigothic fortress.

In 974, Count García Fernández of Castile granted it a charter - considered the first fuero in all of Castile, notably allowing any peasant who owned a horse to be considered equal to minor nobility. The town below exemplifies Jacobean urbanism, with all houses aligned along the Camino de Santiago. This street-path is the longest of its kind on the entire pilgrimage route and contains notable religious and civil buildings.

As an important Camino stage, it maintained several hospitals. A distinctive stone cross displays a TAU symbol rather than the traditional Latin cross, possibly commemorating the Antonine Order who operated a monastery and hospital outside town, treating pilgrims afflicted with St. Anthony's Fire.

The entire town holds Cultural Heritage status as a Historic Ensemble and integral part of the Camino de Santiago. The medieval castle ruins, site of Queen Leonor of Castile's assassination in 1359 by order of her nephew Pedro I, underwent restoration for tourist visits completed in 2013. The Church of San Juan stands as the town's architectural centerpiece along the street-camino.

This fortress-like structure with its slender tower contains Romanesque elements at its base and features an immense three-nave interior with palm-like vaulted ceilings. Originally belonging to the Templars, it later passed to the Hospitaller Brothers of St. Anthony.

Notable features include a stunning five-pointed star rose window with mystical symbolism, a 14th-century mudéjar cloister with astrological references and Gómez Sandoval family shields, funeral chapels with Flemish retables, and an 18th-century rococo altarpiece from the former San Antón monastery. Outside town stand ruins of the Royal Hospital of San Antón, founded by Alfonso VII in 1146, where Antonine monks treated pilgrims suffering from St. Anthony's Fire.

Only the entrance arch remains of this once-important institution.

Castrojeriz stretches along the Camino de Santiago below a hilltop castle. Its main street, the Calle Real, is the pilgrim route itself and the longest such street on the Camino, called calle de Oriente as far as the Plaza Mayor and calle de Poniente beyond it. The castle's origins go back to a first-century Roman tower on the site of an older hillfort, and in 1359 it saw the killing of Queen Leonor of Castile.

Along the street stand the Gothic church of Santo Domingo, with a Plateresque doorway, and, at the western end, San Juan, with a fourteenth-century Mudéjar cloister and a five-pointed star rose window. In the Manzano quarter, Santa María del Manzano, begun in 1214, houses the Museo de Arte Sacro, with medieval carvings and Flemish paintings. About three kilometres out stand the ruins of San Antón, where Antonine monks treated pilgrims with St Anthony's Fire.

Castrojeriz joined Los Pueblos Más Bonitos de España in 2023. The label is awarded by a private association, not the state: a village applies and is audited against around 40 criteria, from how its historic buildings are conserved to the upkeep of its streets, and members are reviewed and can lose it. Castrojeriz is one of 31 members in Castilla y León, out of 126 in Spain. See all heritage towns in Castilla y León.

Access is via Bilbao, Madrid, or Santander airports, with no train service available. The village is easily walkable, with several ATMs including an Ibercaja branch and multiple grocery stores. Various bars serving food and restaurants provide dining options.

The Proxima grocery store offers small round prepared pizzas for €3 (June 2025). Drinking water fountains are located throughout the village.
