Pont du Diable

Puente del Diablo is a two-arch bridge spanning the Tiron River that connects the road from Pradoluengo with San Miguel de Pedroso village. The structure carries the BU-811 road and includes a water measurement station.

The original structure was completed in 1909 and was replaced by a concrete bridge in 1929 that succeeded an earlier wooden crossing called Magazos. Multiple construction failures led workers to associate the bridge with the devil.

Local stories speak of legendary creatures with duck feet and female bodies from Basque mythology that were said to inhabit this area. These beings became woven into the identity of the place and its waters.

The bridge is easily accessible via the BU-811 road and offers clear views across the river valley and landscape. Visitors can best explore it on foot and view it from the surrounding countryside.

River floods repeatedly destroyed construction attempts during the early building phase, leading workers to resort to supernatural explanations for the failures. This misfortune gave the structure its enduring name that remains today.
