It functioned as a state prison for high-profile captives, including the infante Ferdinand of Aragon.
The castle grounds were used for centuries as a 'pósito' or public granary to store grain for the region during times of scarcity.
The brick construction uses a technique known as 'verdugadas', where bands of stone or masonry are layered between brick rows for structural reinforcement.
Queen Isabella I of Castile spent part of her childhood within the walls of the Arévalo fortress.
The fortification is integrated into the town's defensive wall system, though it was designed to be independent from the main town fortifications.
The current interior layout has been significantly altered to accommodate grain storage and modern administrative office functions.
The castle's defensive design lacks traditional battlements on some sections due to its secondary role as a palatial residence for noble families.
The Castillo de Arévalo, also known as the Palacio de los Condes de Montejo, is a 15th-century mudéjar-style fortification located at the confluence of the Adaja and Arevalillo rivers. It is one of the best-preserved examples of military-residential architecture in the province of Ávila. Historically, it served as a state prison, housing notable figures including King Francis I of France after the Battle of Pavia. The structure features a distinctive pentagonal floor plan with a massive keep and original brickwork characteristic of the Castilian mudéjar tradition. It currently serves as the headquarters for the Spanish Agricultural Guarantee Fund (FEGA). Portions of the site are open to the public for guided tours that explain its transition from a fortress to a royal residence and its long-term use as a grain silo. The site reflects the defensive needs of medieval Castile combined with the decorative masonry techniques of Moorish artisans.
The elevated path on the riverbank across from the castle provides the best angle to capture the full pentagonal layout and the brickwork of the keep.
Combine your visit with a walking tour of the town’s Romanesque-Mudéjar churches, which are within walking distance.
Check the local municipal tourism office for tour availability, as access to the interior is strictly regulated by the current administrative use.
Wear comfortable walking shoes, as the perimeter path around the castle features uneven historic paving stones.
Do not expect a fully furnished medieval museum interior; the focus is on the exterior architecture and historical narrative.
Closed on Mondays and most public holidays; group visits often require advance booking through the local tourism office.
Maintain a quiet demeanor as the building functions as an active government office; do not enter restricted areas marked for employees.
