Viaduc ferroviaire d'Albi
The Albi Railway Viaduct — the Viaduc ferroviaire d'Albi, also called the viaduc de Castelviel — is a 19th-century brick-and-stone arch bridge that carries the railway line across the Tarn on the edge of Albi's UNESCO-listed old town. Completed on 15 December 1869 and still in active service, its low curve of seven arches reads as a continuation of the city's signature red-brick architecture, set against cathedral and river.
What makes it worth a detour is how the structure has been given a second life for visitors: a slender pedestrian-and-cycle footbridge now cantilevers along the viaduct, letting you walk or pedal from the Cité épiscopale to the green riverbank at Pratgraussals while trains pass overhead. Add the bridge's claim on art history — Henri de Toulouse-Lautrec, an Albi native, painted it in 1882 — and this unassuming railway crossing becomes one of the most quietly charming viewpoints in the town.
