Castillo de Bijuesca

Castillo de Bijuesca is a medieval fortress standing above the village of Bijuesca, in the province of Zaragoza, within the Comunidad de Calatayud region of Aragon, Spain.

When was the castle built?

The fortress dates back to the 14th century, raised as a border stronghold between the Crown of Aragon and Castile. It sits on a rocky spur, only a few dozen kilometers from the border with the province of Soria — a location that explains its military importance at the time.

What role did it play in the War of the Two Pedros?

In 1357, King Peter IV of Aragon ordered the reinforcement of both the castle and the neighboring church, preparing the site for confrontation with Castile. A year later, in 1358, Bijuesca became one of the first castles captured by Peter I of Castile, known as "the Cruel." Command of the fortress was entrusted to captain Gómez Carrillo, lord of the Torreón de las Henestrosas — the same Peter the Cruel later had him executed on accusations of treason.

Aragonese forces retook the castle, only to lose it again during the 1362 offensive. The fortress eventually returned to Peter IV, who ordered its demolition. The order was carried out only partially, which is why sections of the walls have survived to this day.

What does the castle look like today?

The fortress is arranged in three defensive enclosures, stepped across a rocky ridge. The middle enclosure follows an oval plan about 70 meters along its main axis, with walls — mostly ruined — that follow the shape of the terrain. The upper enclosure is elongated, roughly 40 meters long and 20 to 30 meters wide; here, stone walls with battlements and arrow slits still stand, giving visitors a sense of the fortress's original profile.

Can visitors go inside?

The castle belongs to the municipality of Bijuesca, and entry is free. It is listed as a catalogued asset of Aragon's cultural heritage, yet it also appears on Hispania Nostra's Red List of endangered heritage sites — the organization highlights the ongoing deterioration of the walls despite conservation efforts.

What else is there to see nearby?

Bijuesca lies about 50 km from Calatayud and roughly 139 km from Zaragoza, in a scenic borderland between Aragon and Castile. The sight of the fortress perched on its rocky spur, surrounded by the hills of the Comunidad de Calatayud, is itself one of the main reasons to visit — this is a place valued more for its landscape and history than for tourist infrastructure.
