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.

The Castle of the Dukes of Frías was declared a Site of Cultural Interest on April 22, 1949. It is situated on a rocky promontory overlooking the town and almost the entire Tobalina Valley. The oldest surviving remains date from the late 12th and early 13th centuries, but most of what remains is from the 15th century. Visitors can explore the large parade ground, part of the curtain wall, and the rampart walk, and climb the keep. Opening hours are daily from 10:30 a.m. to 2:00 p.m. and from 4:00 p.m. to 7:30 p.m., and the entrance fee is €2.
