Bridge in Morlaix

Built in 1861 to carry the Brest–Paris railway, this colossal viaduct is unmissable. During daylight hours you can walk along the lower level for a great view of the town; the viaduct is lit up at night. You can climb up the lane of Venelle de la Roche to access the viaduct entrance at the west end, and consider walking up this delightful lane afterwards for views over town.
