Montreuil-sur-Mer

Montreuil sits on a hill above the Canche about fifteen kilometres inland, and the sea part of the name is a leftover: the estuary silted up centuries ago and the port went with it, but the name stayed. The town is ringed by around three kilometres of ramparts, medieval in origin and reworked by Vauban, walkable in a full circuit with views over the valley. A citadel stands at one end. Victor Hugo passed through in 1837 and set part of Les Miserables here, with Valjean as the town's mayor, and an outdoor production of the novel is staged in the citadel each summer by hundreds of local volunteers.

What you actually see

• The rampart circuit - three kilometres of walls walked right round the town.
• The citadel - Vauban-era fortifications at the western end.
• The cobbled streets - the old town inside the walls, including the Cavee Saint-Firmin.
• The Les Miserables production - a volunteer summer staging in the citadel.

When to go

April to October; the Les Miserables performances run in summer over a few nights and book out. The rampart walk is best in the evening. Winter is quiet with limited opening.

Honest expectations

The sea is no longer there despite the name. The town is small and quiet, with the ramparts the main attraction. The summer production is in French and sells out well ahead.
