On the Moselle, between Metz and Luxembourg, Thionville first appears through its belfry, which rises above the rooftops like a raised finger. River boats moor at the quay, a few minutes' walk from the old centre, and the town can be explored at a leisurely pace in a morning or an afternoon. Long held by the counts and then the dukes of Luxembourg, a fortified town fought over for centuries, this Lorraine town has kept sturdy monuments and an identity all its own from its border past.

The Tour aux Puces, a memory in stone

On the quay itself, between the courthouse and the town hall, stands the town's oldest monument: the Tour aux Puces, the former keep of the castle of the Counts of Luxembourg, built in the 11th and 12th centuries. Its silhouette intrigues, with fourteen sides that make it look round from afar. Since 1905, it has housed the local archaeology museum, whose collections range from prehistoric tools to medieval remains found in the region. The visit takes an hour and gives a solid grounding for the rest of the walk.

The belfry and the streets of the centre

At the end of the 14th century, obtaining the right to build a watchtower was a privilege: the belfry was the proof and the symbol of civic liberties. At the top, a carillon of four bells, cast between 1656 and 1844, still marks the hours. Around it, the signposted old-centre circuit starts from the market square, lined with arcades and classical façades, and leads to Saint-Maximin Church, a vast neoclassical building known for its old paintings and remarkable organ.

The banks of the Moselle

Back toward the water, the landscaped quays invite a walk along the river, where barges and pleasure boats glide by. The park and the footbridge offer peaceful views of the opposite bank, and weekend anglers set up beneath the trees. Interpretive panels along the way tell of the river's boating history, when it was once crowded with timber rafts and flat-bottomed barges. Here the Moselle acts as a link: downstream, it crosses the border and heads toward nearby Luxembourg, whose cross-border workers drive the local economy morning and evening.

A table between two worlds

Local cuisine embraces its dual culture. On the menus of winstubs and brasseries you'll find quiche lorraine, meat pie, ham hock and river fish, paired with Moselle wines, light whites produced on both sides of the border. Bakeries sell Commercy madeleines and pâté lorrain to take away, an ideal snack for the rest of the cruise. In fine weather, the terraces on the market square fill up from noon, and conversations switch from one language to another without anyone batting an eye.

A fortress past

Military history buffs will find plenty in the traces of successive fortifications: Vauban strengthened the town after the French conquest, and barracks from the following centuries still punctuate the urban fabric. This garrison past explains the layout of the centre, compact and easy to explore, where each era has left a building, a gate or a street name. The heritage trail's panels tell of these successive layers without ever weighing down the walk.

The carillon sometimes salutes the boats as they leave. Thionville is no tourist capital and is none the worse for it: it offers river travellers exactly what you hope for from a Moselle stop, stones that speak, quiet banks and a generous table. The river continues north, and you find yourself following the belfry with your eyes until the last bend.
