Santa Marta Castle

Highlight • Castle

Imposing castle a few steps from the town of Pancorbo. Even if it was in an open field, it is worth seeing, but climbing the stairs to the tower, admiring the town below and feeling yourself under the cliffs of the upper mountains... an experience to be repeated.

Frías, picturesque medieval village

Highlight • Settlement

A very charming town. It maintains a medieval urban structure that crowns the castle of the Velasco family and the church of San Vicente. The houses are attached to each other, reminiscent of the hanging houses of Cuenca.

Although Frías only has 267 inhabitants (as of 2022), the place can officially call itself a “city” (ciudad) - making Frías the smallest city in Spain.

Crowned by an imposing hilltop castle, the town of Frías offers cobblestone streets, stone houses and a suspension bridge over the Ebro River. Its old town retains its historic charm, with picturesque squares and a welcoming atmosphere. The town was built in a strategic enclave at the passage of the Ebro River, since Roman times and mainly during the medieval period.
