Castillo de Jalance

Castillo de Jalance is a medieval fortress overlooking the small town of Jalance, in the Ayora-Cofrentes valley, Valencia province. Its ruined but still striking walls follow an unusual polygonal layout and command sweeping views over the surrounding hills.

When was the castle in Jalance built?

The fortification standing today dates back to the 11th century and was raised by Muslim builders on top of the remains of a much older Iberian stronghold. After the Christian conquest the site was repeatedly rebuilt and reinforced, so what visitors see now is a layered mix of construction from several periods.

What happened to the castle after the Reconquista?

The lands of Jalance were taken by James I of Aragon and then handed over to the King of Castile under the Treaty of Almizra. For a time the town formed part of the holdings of Infante Juan Manuel, one of the most powerful noblemen of his era. In 1281, an agreement between Peter III of Aragon and Alfonso X of Castile placed the territory definitively within the Kingdom of Valencia. Administratively, Jalance depended first on Jarafuel (until 1535) and later on Cofrentes (until 1564), before gaining its own independent status.

Why was the fortress called "impregnable"?

In the 15th century, the Marquis of Santillana — one of the most influential Castilian writers and statesmen of the period — described the castle as an almost unassailable stronghold. That was no exaggeration: the steep hilltop position combined with a carefully thought-out defensive layout made any assault extremely difficult.

How is the castle laid out?

The fortress follows a rare ten-sided polygonal plan, reinforced with arrow slits and round towers at the corners. It is split into two areas: an upper, heavily fortified enclosure, and a lower albacar — originally an Islamic-era defensive and livestock enclosure — which the Christians later converted into a parade ground used as a refuge for the local population in times of danger.

What role did the castle play in the 19th century?

During the Carlist Wars, the walls were rebuilt so the fortress could once again shelter the townspeople. In 1836 the area around Jalance became a battleground: the town and its castle were defended against attacks led by the Carlist commander Quílez. The episode shows that, centuries after it was first raised, the site still fulfilled its original defensive purpose.

What condition is the castle in today?

Castillo de Jalance survives as a ruin, though recent years have seen consolidation and partial restoration work, making the site safer to explore and easier to read as a fortified structure. The castle hill is also the starting point for local trails, including a birdwatching route that loops around the fortress — drawing both history enthusiasts and nature lovers to the area.
