Ayuntamiento de Valderredible

Ayuntamiento de Valderredible is the town hall of Valderredible, the largest municipality in Cantabria, headquartered in Polientes — the main settlement of the Ebro river valley. The municipality spans 52 villages scattered across more than 298 km², making it one of the largest municipalities by area in all of Spain, while also being one of the least densely populated.

Polientes sits in the southern part of Cantabria, along the upper course of the Ebro river, surrounded by gentle hills and wide valleys. It functions as the natural administrative and commercial hub of the whole valley, hosting local markets and most of the services for residents living in the scattered surrounding villages.

How do you get to Polientes?

Polientes lies on a regional road connecting inland Cantabria with the provinces of Burgos and Palencia, so arriving by car is by far the most practical option. The nearest larger towns are Reinosa and Aguilar de Campoo, both several dozen kilometers away. From Santander, the drive takes over an hour through the mountainous, scenic interior of the region. Public transport in this part of Cantabria is limited, so most visitors rely on their own vehicle.

What is there to see nearby?

The town hall building itself is mainly administrative, but Polientes is the natural starting point for exploring Valderredible, one of the most unusual corners of Cantabria. The region is famous for its unique rock-cut churches (iglesias rupestres), carved directly into sandstone cliffs by early medieval settlers. The most important of them is the church of Santa María de Valverde, the only one still used for regular worship. First recorded in 978 as Santa María de Sotarraña, it belonged to the Infantado de Covarrubias, and by the 12th century to the monastery of Santa María la Real in Aguilar de Campoo. An extensive necropolis survives on its roof, alongside a distinctive bell tower.

Next to the church, an Interpretation Center dedicated to rock-cut architecture explains the Christianization of Cantabria, hermit practices and medieval burial customs. The center opens every day except Mondays, with a symbolic admission fee of one euro. Other rock-cut churches in the valley, such as Campo de Ebro, El Cadalso, Arroyuelos and El Tobazo in Villaescusa de Ebro, can be visited along the road leading toward Polientes for those with more time.

Beyond its rock-cut heritage, Valderredible also preserves numerous examples of Romanesque architecture and traditional rural buildings, with several interpretation points scattered across the valley covering local history, ethnography and astronomy.

When is the best time to visit?

Spring and summer are the best seasons, offering favorable conditions for walking between the scattered villages and exploring the rock-cut churches outdoors. Autumn has its own appeal, as the Ebro valley turns gold and red. Winters in this part of Cantabria tend to be cold and damp, which limits comfortable outdoor sightseeing.
