Castillo de Laguarres

Castillo de Laguarres is a ruined medieval fortress overlooking the Isábena valley, in the municipality of Capella, in the Ribagorza region of the province of Huesca, in Aragón, Spain.

Where is it located?

The ruins crown the Sierra de Laguarres, at roughly 1,100–1,130 metres above sea level, right above the village of Laguarres. From this vantage point the view stretches over the Barasona reservoir, the confluence of the Ésera and Isábena rivers, and the silhouette of Mount Turbón, with the Pyrenean peaks visible on clear days.

How do you get there?

The most straightforward approach is by road from Benabarre towards Laguarres. Around the seventh kilometre of that road, before the pass, a forest track branches off leading up to the repeater towers that now stand beside the castle ruins. The final stretch is done on foot, along a moderately difficult route that crosses pine forest, Mediterranean scrubland and meadows — comfortable footwear and water are worth bringing. The nearby towns of Graus and Benabarre make convenient bases for exploring the area.

What will you see?

What survives of the fortress is the base of a circular tower, about eight metres in diameter and up to three metres high, built in sillarejo (small roughly hewn stone). The tower sits on an earthen platform that was likely once reinforced by a defensive wall; sheer rock drops gave natural protection on the north, east and west sides, while the south side would have needed additional fortification. No door opening or other architectural details remain visible today — what's left is a striking ruin set in mountain scenery, standing alongside modern telecommunications towers.

What's the history behind it?

The castle's origins go back to the 10th century, when it served as one of the principal Muslim strongholds facing the Christian county of Ribagorza, alongside the fortresses of Lascuarre and Castigaleu. Excavations have turned up grey-paste pottery fragments dated to the mid-11th century. Around 1060, King Ramiro I captured the castle, ending its military relevance — together with Lascuarre it was absorbed into the barony of Castro, held in the late 13th century by Felipe de Saluces (documented in 1292). The site briefly regained significance during the Peninsular War against Napoleon's troops, when a guerrilla fighter known as the "Beneficiado de Laguarres" used the surrounding hills against the French. In 2006 the site was declared a Bien de Interés Cultural (BIC) under the archaeological zone category.

When should you visit?

Spring brings wildflowers across the surrounding meadows, while autumn covers the forests in gold. In summer, an early-morning visit is best, since the exposed summit gets hot and sun-beaten for most of the day.
