Pont-Vieux d'Espalion, Medieval bridge in Espalion, France.

The Pont-Vieux d'Espalion is a pedestrian stone bridge over the Lot, built of red sandstone in a Gothic style. It has four arches; the central one is the tallest and widest, and the last on the right bank is a round arch rebuilt in 1724. Triangular cutwaters rise to the parapet, and a metal cross set in 1728 stands on one of these refuges.

This structure was built in the 13th century and originally included three defensive towers and a drawbridge for protection. These military features were removed during renovations carried out in the 18th century.

The bridge lies on the routes to Santiago de Compostela and has been listed as UNESCO World Heritage since 1998. Its name comes from the Latin pons vetus, "old bridge". Each year in late May, the transhumance of cattle toward the Aubrac passes over it, keeping a pastoral tradition alive in the town.

The bridge welcomes both pedestrians and cyclists and connects both sides of town easily. Watch your footing on the stone surface and note the raised edges if you are bringing a bicycle.

The central arch rises higher than its neighbors to handle the river's rapid floods during heavy rains. An iron cross placed in 1728 marks the southeast side and stands as a historical marker from that era.
