Why go
The bridges retain their historic name even though their roofs disappeared long ago. Walking across them brings the medieval towers and water channels into view at eye level. That close perspective offers a distinct visit from the elevated Barrage Vauban terrace just beyond.
What to look for
- Cross the bridges among three surviving medieval defensive towers.
Useful to know
- Cross the bridges for a close view of the towers, then continue to Barrage Vauban for the wider panorama.
