Frías sits on the steep tuff-rock plateau known since ancient times as “La Muela.” The town’s medieval heritage is reflected in several distinct types of architecture: the castle, the Casas Colgadas built against the rock, the town wall and the fortified bridge over the Ebro. The medieval town was recognized as a Bien de Interés Cultural in 2005. To plan your trip, you can first decide whether you are mainly interested in military architecture and the townscape, or in the Fiesta del Capitán.

Rock, Houses and Town Wall

The Casas Colgadas de Frías are built against the cliff face and form an extension of the northern defensive wall. The houses, built close together, create steep, cobbled streets with a medieval character. In this way, the terrain, buildings and fortifications are clearly connected: the Casas are part of the townscape and also extend a defensive line.

On the south side, a 13th-century wall protects the town. It originally had three entrance gates: the Gate of Medina, the Postigo and the Cadena. The Cadena Gate no longer exists. Together with the northern extension of the wall formed by the Casas Colgadas, the southern wall shows another aspect of the fortifications: it protects the town, while the houses to the north are incorporated into the defensive line.

Castle and Views

Construction of the Castillo de los Duques de Frías began in the 12th century. Its defensive complex includes a drawbridge, a moat carved into the rock, high walls and battlements. The moat incorporates the terrain directly into the fortifications. From the upper part of the keep and from the three windows with Romanesque capitals set into the masonry, there are excellent views of the town and its surroundings.

The Fortified Bridge over the Ebro

The Puente Medieval de Frías is a fortified medieval bridge over the Ebro. Historically, its tower was used to control passage and collect a bridge toll. Together with the Castillo, it illustrates two different aspects of military architecture: the castle is defined by its moat, high walls and battlements, while the bridge combines fortifications with control of a river crossing. The two structures can thus be viewed in terms of their different functions.

Fiesta del Capitán

The Fiesta del Capitán takes place on the Sunday closest to June 24, the feast day of Saint John. It commemorates the 15th-century revolt of the people of Frías against the Count of Haro. Recurring traditions include processions through Frías, dancers, musicians, decorated horses and the Danza de San Juan. The specific program may vary from year to year; if you would like to include the festival in your trip, check the dates and program for the relevant year.
