Tips from the Community

JULIO TENDERO ROSELL
January 7, 2026, Frías Medieval Bridge

Built to span the Ebro River, this stone bridge is an impressive 143 meters long and features nine arches. The central section boasts a slender defensive tower, adorned with battlements and arrow slits, added in the 14th century. In medieval times, passage was controlled from this tower: anyone wishing to cross the bridge had to pay a toll of a few maravedís. The bridge offers one of the best views of the city of Frías.

Amurrio was traditionally known as "El Crucero," a meeting point for routes between Castile and the Cantabrian ports. In the town center, the Ugarte Tower House (18th century), now the Cultural Center, the San Antón de Armuru Chapel (16th century), and the Church of Santa María with its 25-bell carillon, one of the largest in the Basque Country, stand out.
