Castro del Río Castle

The Fortress of the Cervantine Town

Palimpsest in the Countryside

This castle is the keystone of the Town. Sitting on a meander of the Guadajoz river, it rises above Roman foundations and the old Almohad medina. It was here where the history of literature and war crossed paths.

Its walls hold the memory of Miguel de Cervantes, who suffered imprisonment in the town while conceiving Don Quixote. In the 20th century, its towers served as a radio post in the Civil War, leaving graffiti that are today living history alongside medieval architecture.

The Radio Tower

During the Civil War (1936), the rebel side installed a transmitter in the Cylindrical Tower. Soldiers left graffiti and technical diagrams on the walls that are still preserved.

La Cantamora
The Legend of the Cantamora

It is told that on the night of Saint Blaise, a young Moorish woman appears combing her hair and singing laments for her lost love, foretelling misfortunes to whoever sees her.

Octagonal Cistern
Hidden Geometry

The northeast tower is circular on the outside to deflect projectiles, but octagonal on the inside, housing a monumental 80 m³ cistern that guaranteed survival.

Roman Foundations
Castra Soricaria

The name “Castro” comes from the Latin Castra (camp). The castle sits on Roman foundations that controlled the oil trade along the Salsum river (Guadajoz).

Anatomy of the Fortress

Castro del Río Castle Architecture

A seigniorial castle inserted into an Almohad precinct, adapted for defense and administrative life over the centuries.

🏰
Keep

Recently restored and open to the public, this prismatic structure stands out for its rammed earth construction (“tapial”), a legacy of the Almohad technique. It served as the last defensive redoubt and symbol of seigniorial power over the town, offering incomparable panoramic views today.

Power It is the symbol of seigniorial authority, protecting the main gate. Its rammed earth construction absorbed artillery impacts better.
🧱
Walled Precinct

The castle is not an isolated building but an integral part of the wall that embraces the Barrio de la Villa. This fortified enclosure of Almohad origin (12th century) protected the medina and was reused and reinforced after the Christian conquest, creating an impregnable defensive complex.

Base The Christian castle was not built from scratch but “attached” to the wall of the Islamic medina, taking advantage of its perimeter.
Cylindrical Tower

Located in the northeast corner, this tower presents a curious duality: circular plan on the outside to repel projectiles and octagonal plan on the inside. Its walls preserve graffiti and technical diagrams of its use as a radio station during the Spanish Civil War.

Double Face Its curved exterior deflected attacks, while its geometric interior housed the cistern and served as a command and communications post.
💧
The Cistern

Hidden under the Cylindrical Tower, there is a monumental water tank with a capacity of 80,000 liters. Built with hydraulic mastery, it guaranteed the supply to the garrison and the town’s population in case of prolonged siege or drought.

Ingenuity The oculus of the vault acted as an impluvium, collecting rainwater from the rooftops to fill the vital cistern.
🚪
Access Gate

Access to the noble precinct was through an ashlar portal with a semicircular arch, defensively flanked. This entrance marked the boundary between the common town and the space reserved for the warden or lord of the castle.

Hierarchy The carved stone of the door contrasts with the earthen walls, marking the passage to the feudal lord’s space of power.
🎭
Parade Ground

In the heart of the fortress opens a rectangular space of about 500 square meters. Once a place for troop formation and logistical distribution, today it is a space recovered for culture and visitor enjoyment.

Stage Former place of arms, today its acoustics and surroundings make it the perfect stage for theater and cultural events.
