Namur is worth a detour. Cross its beautiful bridge. A citadel on the Champeau hill dominates the town. You can get there along the Route Merveilleuse. This bastion of the end of the 15th and 16th century is an illustration of defensive architecture. In the centre of the town, the Oignies priory treasury reveals work by an early 13th century goldsmith. Otherwise, the Saint-Loup church stands out for its baroque style.
