Castle of Palenzuela

The Castle of Palenzuela stands at the eastern edge of the small town of Palenzuela, in the province of Palencia, in the Cerrato region of Castile and León. Perched on a terrace overlooking the Arlanza valley, the ruins date back over a thousand years, and although only fragments of the original fortress remain, the site still impresses with its scale and layered history.

How do you get there?

Palenzuela sits at the heart of the Cerrato region, close to where the Arlanza and Arlanzón rivers meet, within the province of Palencia. The town is best reached by car along the local roads connecting it to neighbouring villages in the area. The castle itself sits on raised ground at the eastern edge of the town, so from the town centre it's a short but slightly uphill walk to reach the ruins.

What will you see?

Of the original fortress, built in the 9th century along the town wall, only the ruins of two towers and the base of a third survive today, together with sections of wall showing the openings of former doors and windows. The castle was originally built with three towers finished in ashlar stone, a design that made it one of the more significant strongholds in the region.

The site's history is turbulent. The fortress was already documented in the year 850, yet the town still suffered two Arab raids in 919. In 1295, when Palenzuela was under the lordship of Juan Núñez de Lara, who rebelled against María de Molina, regent during the minority of Ferdinand IV, the town withstood a six-month siege before returning to royal control. In September 1425, King John II convened the Cortes in Palenzuela, held at the convent of San Francisco just outside the town walls — the moment of the town's greatest splendour. The town passed to the Admirals of Castile in 1429, and in 1444 it became the setting for a confrontation between King John II of Castile and John of Navarre.

The castle's decline came from nature rather than war: in 1641, a powerful storm brought down part of the town wall, damaged the main gate, and destroyed part of the castle's towers. The town later endured occupation by French troops during the Peninsular War of 1808–1814.

It's worth pairing a visit to the castle with a walk to Palenzuela's other landmarks — a striking Gothic church built between the 13th and 15th centuries, and the Arco de la Paz (Arch of Peace), one of the best-preserved remnants of the town's old walls.

When should you visit?

Since the ruins are open-air with no roof or shelter, spring and autumn are the most comfortable seasons, when temperatures in the Cerrato region are milder than the hot summers or cold winters. Morning hours also offer the best light for photos from the terrace overlooking the Arlanza valley.
