Four brick chimneys are reflected in perfectly still water: that of the Mittelland Canal, where ships moor at the foot of one of the largest car factories in the world. Wolfsburg at first puzzles the cruise passenger used to medieval bell towers. Here, almost everything was born in the 20th century, and the call is experienced as a dive into industrial Germany, its feats, its design and its contrasts.

A canal for a main artery

The navigation itself changes register: on this artificial waterway, the surface stays flat, the banks run straight, and locks replace meanders. The mooring places passengers at the exact centre of the city, with the train station and pedestrian bridges a few minutes away, the factory on one side and the neighbourhoods on the other. On the north bank, the production buildings stretch for several kilometres, a reminder of the extraordinary scale of the place. The landscaped banks also lend themselves to a morning walk, and several passengers take advantage of it before lunch. Rarely will a river call have required so little logistics.

A city born in 1938

Wolfsburg was founded from scratch to house the workers of the Volkswagen factory, and its layout retains that logic: the canal and the railway separate production, to the north, from daily life, to the south. The Porschestrasse, a long pedestrian thoroughfare, concentrates shops, cafés and terraces up to the art museum that closes off the vista. Yet the city takes its name from a Renaissance castle set amid greenery, Schloss Wolfsburg, now a municipal museum; a leisurely half-hour walk lets you go and greet this unexpected elder in the middle of such a young city. Along the way, you notice how much greenery the urban planners have sown between the buildings.

The Autostadt, a waterside showcase

Right across from the mooring, the Autostadt spreads its pavilions and landscaped lagoons along the bank. Each brand of the group has its own architect-designed showcase, and the ZeitHaus lines up the automobiles that defined their era, from the Beetle to prototypes. The most hypnotic sight remains the two glass towers: mechanical arms silently move hundreds of new cars inside, awaited by customers who have come from all over the country to take delivery of their vehicle. The park can fill an entire half-day; passengers in a hurry will settle for the ZeitHaus and a stroll along the pools. A tasty wink: the carmaker even produces its own currywurst, labelled as an "original part" and now a source of local pride.

Phaeno, the concrete mountain

On the other side of the pedestrian bridge, the Phaeno science centre seems to rest on concrete cones, a futuristic silhouette designed by Zaha Hadid. Inside, hundreds of experiments invite you to touch, blow, and set off whirlwinds and lightning; families linger for hours on end. The building alone is worth a look, so fully does it embrace its appearance of a vessel set down in the middle of the streets. Lovers of greenery will prefer the Allerpark, a vast expanse of lawns and ponds where residents swim in summer, a few minutes from the bank.

Port of call at a glance

Once the lines are cast off, the brick chimneys slowly recede along the axis of the canal. This stop stands out in a river itinerary, and that is its strength: after abbeys and vineyards, here is an entire day devoted to mechanical genius and the imagination of the last century's builders. Conversations over the evening meal that night almost always turn, and for a long time, to cars.
