Out of the eight bridges that Gustave Eiffel had engineered for the Girona railway company, the bridge in Colera has an important function of transporting passengers and cargo between Spain and France.
The bridge was erected in 1878 over the ravine where the town of Colera is nestled. During the Spanish Civil war (1936-1939), the bridge was a key strategic site for both sides and, despite numerous seaside and air attacks, has survived thanks to the artillery troops and antiaircraft systems of the Republican forces.
