Montreuil

Montreuil's unofficial moniker of sur-Mer hints at its past status as a port town. While it has never been on the seafront, the river Canche was wider and deeper until the late Middle Ages, permitting seagoing vessels to use Montreuil as a harbour. After this period, the Canche silted up and Montreuil became fully landlocked. The river's port is now further downstream at Étaples.

By car

Originally a stop on the main Paris to Calais road, the N1 now bypasses the town. If arriving via the A16, leave at exits 25 or 26.
