Castillo de Juslibol

Castillo de Juslibol is a medieval fortress ruin perched on a hill near the Ebro River, with surviving sections of defensive walls and a partly vaulted water cistern. The remains reveal how the structure was built to control movement along the river and store essential supplies.

The fortress was built in the 11th century as a Muslim stronghold called Mezi Meeger and played a decisive role during the Christian reconquest of Zaragoza in 1118. Its position made it essential for controlling the valley during periods of conflict between regional powers.

The name Juslibol comes from the Crusader battle cry 'Deus lo volt', meaning 'God wills it' in medieval times. This origin reflects the religious conflicts that shaped the region's history.

The ruins are reachable through the rural neighborhood of Juslibol, located northwest of Zaragoza's downtown area. The site sits on a hilltop with open surroundings, so sturdy footwear and sun protection are advisable when visiting.

The fortress served as a key observation post within a defensive network that stretched across the region to protect the ancient city of Saraqusta. From this vantage point, visitors can understand the strategic thinking behind its placement.
