The castle was significantly modified by the Order of Santiago after they took control of the region in the 13th century.
The Church of Santo Domingo within the castle grounds was destroyed by fire during the Peninsular War against Napoleon's troops.
The fortress is constructed on a vertical needle of rock, which historically made it nearly impossible to attack from the rear.
The town of La Iruela below was historically a dependency of the Archbishopric of Toledo.
The structure includes an ancient cistern carved directly into the rock to collect rainwater for prolonged sieges.
Castillo de la Iruela is a Templar-era fortress perched on a sheer rocky outcrop overlooking the town of La Iruela in the Sierra de Cazorla. The structure incorporates an Almohad-style defensive wall and a prominent keep built upon a precarious limestone cliff. Visitors traverse narrow staircases and walkways that lead to the highest point, providing views over the Guadalquivir valley. The site contains the ruins of the Church of Santo Domingo, which features Renaissance elements and was built inside the fortress walls after the Christian reconquest. The defensive complex served as a strategic watchpoint for the Adelantamiento of Cazorla during the Middle Ages. Its layout follows the natural topography of the crag, necessitating a steep climb to access the primary towers.
The highest platform of the keep looking back down toward the Church of Santo Domingo and the valley below.
Wear footwear with high-traction soles as the ancient stone stairs are steep, uneven, and can be slippery.
Individuals with a fear of heights should exercise caution, as many viewing platforms are open and lack modern handrails.
Visit during the shoulder season to avoid intense mid-day heat, as there is minimal shade within the stone ruins.
Attempting the ascent in flip-flops or open-toed sandals, as the loose gravel and steep stone steps present a significant tripping hazard.
Occasionally closed on Mondays or during periods of extreme weather; check the municipal website before travel.
No specific dress code, but sturdy, closed-toe walking shoes are strongly recommended for safety.
