If you're lucky enough to discover Nantes for a weekend or a few days, there will inevitably be that revelatory moment during your visit: the one where you let yourself be guided by the city's common thread — a green line. Literally.
Discreet but continuous, this green line painted on the ground crosses the city, connects its neighbourhoods and invites you to keep moving without overthinking it. And above all, it transforms the way you visit. This line is the Voyage à Nantes. An artistic trail conceived as a guiding thread through the city, linking historic monuments, contemporary works and cultural venues.
But above all, it plays a far more interesting role: it becomes a gateway to understanding Nantes as a cultural city. Because following this line isn't just about moving from one point to another. It's about grasping the way in which the city was built, transformed and reinvented around culture…
What is the green line of the Voyage à Nantes? It's a line painted on the ground that connects more than 70 artistic and heritage stops along over 20 km across the city. Created in 2011, it transforms Nantes into an open-air museum.
Where should you start? Anywhere. But the most convenient starting points are the Château des ducs de Bretagne, the train station (on the Jardin des Plantes side) and the Île de Nantes.
How long does it take to follow? The complete trail takes 1 to 2 days. There's no obligation to do it all: you can join it for a few hundred metres and pick it up again further along.
Do you have to pay to access the trail? No, the green line is free and accessible at any time. Some stops (museums, Les Machines de l'île) are ticketed.
The green line is a line painted on the ground that runs from one end of Nantes to the other, connecting the key stops of the city's artistic trail. Discreet but continuous, it allows you to move from one discovery to the next without a map or an app. And above all, it completely transforms the way you visit!
Created in 2011, the Voyage à Nantes has gradually established itself as a structuring project well beyond a summer event. Its ambition: to make art accessible to everyone by integrating it directly into the public space.
What distinguishes this trail is the way artworks are embedded in the city rather than in dedicated venues. They enter into dialogue with one another, with the spaces they occupy, and with passers-by. The city itself becomes an artistic trail.
What truly sets this trail apart is the way it adapts to your own pace. You can follow it for a few hundred metres, then pick it up again later; you can use it to structure your day, or simply let it inspire you. There's no mandatory starting point, no imposed direction.
This flexibility completely changes the experience: you move away from an "optimised" visit and into a freer, more intuitive exploration — one where you accept that you won't see everything, but that you'll feel it all more deeply.
The Voyage à Nantes trail extends over more than 20 kilometres across the city. It connects more than 70 stops, spanning artworks, monuments, museums and cultural venues. Together they form what the city calls a "dispersed monument": a unique trail where each stop is part of a whole. The full route can be found here.

This is without doubt one of the most appealing aspects: you can start anywhere. That said, a few places are particularly convenient as entry points:
And that's precisely what makes the trail so enjoyable: it slots into your own rhythm of discovery.
To understand Nantes today, you have to go back to its past. A port and industrial city, it was long shaped by its maritime activities and shipyards. When these went into decline, the question of reinvention became unavoidable.
Rather than erasing that history, Nantes chose to transform it. Former industrial sites were reclaimed, the quays reimagined, and culture became a central lever of this transformation.
The Île de Nantes is the most visible example: a territory in constant evolution, where industrial memory and contemporary creation coexist.
What strikes you in Nantes is the place that culture occupies in public space. It isn't reserved for a handful of institutions or an initiated audience. It is part of everyday life, visible in the streets, in the parks and along the quays. A work of art can appear around a street corner, an installation integrate itself into a landscape, a building become an artistic object in its own right.
The Voyage à Nantes embodies this approach — but doesn't exhaust it. Many cultural venues (museums, galleries, repurposed industrial spaces, hybrid venues…) all contribute to this dynamic.
The Château des ducs de Bretagne illustrates this cohabitation well: a 15th-century historic monument, it today houses a history museum that tells the story of the city's major transformations.

The Passage Pommeraye, with its 19th-century Neo-Renaissance architecture, also continues to thrive between commerce and leisurely wandering, without freezing itself into a museum-like role.
In parallel, contemporary art is inscribed directly into the urban fabric. The works of the Voyage à Nantes are not confined to museums: they are installed in the street, on the quays, in the parks. Some are monumental, others more discreet, but all contribute to the idea of a city transformed into a permanent exhibition space.
On the Île de Nantes, Les Machines de l'île perfectly illustrate this logic by transforming a former industrial site into a space of artistic experimentation.

Some neighbourhoods, such as Bas-Chantenay, are still in full transformation. They bear witness to a city that continues to evolve, to change, to reinvent itself. And perhaps that is where Nantes' singularity lies: in this capacity to never stand still.
What also characterises Nantes is its ability to offer a continuous cultural programme. Temporary exhibitions, events, ephemeral installations… The city evolves with the seasons. Some works appear, others disappear, making each visit different. You don't visit Nantes once and for all: you come back, and you discover something new.
As you follow the trail (and its detours), you move from one neighbourhood to another, each with its own identity. The Bouffay district evokes medieval Nantes, with its narrow alleyways and lively atmosphere. The Île de Nantes reflects the city's contemporary transformation, between repurposed industrial spaces and new uses. The banks of the Loire offer a more open space, perfect for strolling and contemplation.

The green line functions above all as a navigation aid. It allows you to find your bearings easily in the city and move from one discovery to the next without needing a map or an app. But it doesn't claim to show you everything.
A significant part of Nantes' cultural richness lies precisely off the trail. If you take the time to step aside, you can stumble upon equally interesting places — sometimes more discreet, but essential for understanding the city.
For example, the Musée d'arts de Nantes, located a short walk from the train station, is well worth a visit for its collections ranging from the 13th century to contemporary art, housed in a building that blends classical architecture with a modern extension.
A little further afield, the FRAC des Pays de la Loire (in Carquefou, accessible by public transport) offers a programme focused on contemporary creation, often more experimental.
In a different register, Le Lieu Unique (even if it sits close to the trail) operates as a genuine cultural laboratory, with exhibitions, performances, and also living spaces where you can simply spend time.

You can also venture as far as Stereolux, on the Île de Nantes, which blends contemporary music, digital arts and hybrid creations, or explore more alternative spaces such as Pol'n, a committed artistic third place.
And then there are all those galleries, studios and temporary spaces that aren't always signposted but fully contribute to the city's cultural energy. At the end of the day, that may be the real secret: the green line gives you a direction, but it's by allowing yourself to step off it that you discover the full richness of Nantes' cultural scene.
Is the green line of the Voyage à Nantes accessible all year round? Yes. The green line is permanently painted on the ground and the outdoor stops on the trail are accessible year-round. Some indoor or temporary installations may have specific opening hours or seasonal schedules. The summer programme (July–August) is the most extensive.
How much does the Voyage à Nantes trail cost? Following the green line is completely free. Some stops are ticketed: the Château des ducs de Bretagne (museum entry), Les Machines de l'île, or certain associated museums. Budget between €10 and €15 for the main paid attractions.
Can you complete the full trail on foot in one day? The full trail covers more than 20 km and connects more than 70 stops. In an intensive day, you can cover a good portion of it, but it's better to allow two days to avoid feeling rushed and to make the most of each venue. You can also get around by bike or public transport for the longer sections.
Is there an app for following the green line? The Voyage à Nantes offers a downloadable map and a mobile app that geolocates each stop on the trail. That said, the green line on the ground is enough to navigate without an app in the denser areas.
What are Les Machines de l'île de Nantes? Les Machines de l'île is an artistic and mechanical attraction located on the Île de Nantes, on the former shipyard site. Inspired by the universe of Jules Verne and Leonardo da Vinci, highlights include the famous Grand Éléphant (a 12-metre-high mechanical sculpture that roams with visitors on board) and Le Carrousel des Mondes Marins. It is one of the most spectacular stops on the trail.
Is the green line suitable for children? Yes, the trail is very well suited to families. The artistic installations in the public space are accessible without a ticket, and stops like Les Machines de l'île are particularly popular with children. The free-roaming format, with no fixed itinerary, suits young children well.
Following the green line of the Voyage à Nantes means embracing a different way of visiting a city — accepting to be guided while keeping your freedom, and discovering a city where art is everywhere. But it also means understanding that this line is only a starting point. Because Nantes cannot be reduced to a trail: it's a city to explore, to feel, and to rediscover with every visit.
