During cathedral opening hours, it is possible to climb up into the belfry so as to enjoy even more extensive views. When the evening comes, the belfry becomes the residence of the cathedral lookout, who calls out the hour from 10pm until 2am. This tradition has lasted more than 600 years and originally served to warn of fires. Take the market stairs, which start opposite the main entrance to the cathedral. At the very bottom of this stairway, make your way to Place de la Palud; you cross this square, passing in front of a fountain and then along past the city hall. Keep going straight ahead into this pedestrianised area. At first the street descends gently, but then it begins to climb. At the top, when you reach Place St-Laurent, turn left out of this square, taking Rue Pichard. Follow this street, which then heads right and takes you to a pedestrian footbridge. 10 mins.
