The town of Morlaix is dominated by a railway viaduct that is over 50 m high and 258 m long and can be seen from far away. It was built in 1864 to create the railway connection between Paris and Brest. At the time, many buildings had to be demolished for this project. During the Second World War, Allied bombers were supposed to bomb the viaduct, but missed their target and caused great damage to the town. The viaduct can be crossed on foot on the first floor.
