Molina de Aragón Castle

Molina de Aragón Castle crowns a rocky hill above the town of Molina de Aragón, in the province of Guadalajara, Castile-La Mancha. It is the largest surviving fortress in the entire province and one of the most imposing medieval defensive complexes in this corner of Spain.

Where did this fortress come from?

The site's fortifications go back to the 10th and 11th centuries, when Andalusi builders raised an alcazar over an older Celtiberian hillfort. In 1129 the lands of Molina were taken from the Moors by Alfonso I the Battler, king of Aragón, which is how the castle came by its name. For nearly two centuries the lords of Molina enjoyed considerable independence and kept expanding the stronghold, until the fifth in that line of lords, Lady Blanca de Molina, gave it the size and layout still visible today. Through the 19th century the castle served as a military barracks, and in 1875 it was stormed by Carlist troops under General Vallés. The army abandoned the site for good in the early 20th century, and in 1931 the castle was declared a Bien de Interés Cultural, Spain's top heritage protection category.

What will you see on site?

The castle is built as two separate defensive enclosures. The outer one, known as the albacara, forms a rectangle roughly 80 by 40 metres, guarded by several crenellated towers. The inner enclosure, the castle proper, holds six towers, four of which survive in good condition or have been restored. Among them stands the Cubierta tower, also called the Knights' tower, set into the north wall, while the central tower (de las Armas) and the keep, known as Doña Blanca's tower, stand side by side on the southeast. Entry to the inner courtyard runs through the gate in the Veladores tower. The outer enclosure has as many as five gates, including the Traición (Betrayal) gate to the north, the Caballos (Horses) gate to the south, and a gate by the Clock Tower to the west — names that hint at the site's turbulent past.

How do you get there?

Molina de Aragón sits in the eastern part of Guadalajara province, close to the Alto Tajo Natural Park, in a region known for its rugged upland landscape straddling Castile and Aragón. The castle dominates the skyline from almost anywhere in town, since it occupies the highest ground above the old quarter — heading toward the hill that overlooks the historic centre is really all it takes to reach its walls.

When to visit?

Given the upland setting and the region's continental climate, spring and autumn are the most comfortable seasons, sparing visitors both summer heat and winter cold. Because the castle is so open and exposed, a walk along its walls on a clear day also gives the best views over the valley and the town below.
