This vast architectural legacy has garnered attention from international publications such as National Geographic, which have highlighted the uniqueness of these constructions. The selection of the ten most outstanding castles is based on criteria such as accessibility, state of preservation, annual visitor numbers, and their scenic and patrimonial value.

Among the most complete fortresses is the Fortaleza de la Mota, in Alcalá la Real, which stands out for its extensive grounds and diverse visitable dependencies. Meanwhile, the Castillo de Santa Catalina, in the capital, serves as an iconic landmark hosting events throughout the year and featuring an adjacent parador.

For those seeking an immersion in the medieval era, the Castillo de Burgalimar, in Baños de la Encina, and the Castillo de Alcaudete offer enriching experiences with historical reenactments. From a visual perspective, the castles of La Iruela and La Yedra, in Cazorla, impress with their imposing presence from a distance.

The province also features other beautiful fortresses, such as the Castillo de Hornos, La Guardia, Torredonjimeno, and Segura de la Sierra, all worth exploring. The promotion of this heritage is carried out through the Route of the Castles and Battles of the Kingdom of Jaén, which organizes annual events to disseminate its rich history.
