Stand on the courtyard side of the Château des ducs de Bretagne and the city shows you its shape at once: a moated fortress on one side, the Miroir d'eau reflecting it on the other, and the shopping streets of the old town running north. Nantes rewards a traveller who likes to walk between distinct quarters rather than tick off a single monument.
This guide suits anyone with a day or two to spend, whether you are here for the mechanical animals on the Île de Nantes, the 18th-century merchant streets of Île Feydeau, or the parks and gardens that gave the city its green reputation. It covers the sights worth your time, how to string them together, and a few practical notes on timing.
Top things to do in Nantes
1. Château des ducs de Bretagne
A sturdy moated castle, built from 1207 though most of what you see dates from 1466. It served as a ducal and royal seat, notably of Duchess Anne, whose marriages sealed the union of Brittany with France. The courtyard, ramparts and garden are free to enter, and the museum inside covers the city's history.
The main entrance is west by the tourist office, and you can also approach from the north or south; all routes bring you into the courtyard and the ticket office. The museum is open Tuesday to Sunday, 10:00-18:00. Combine the visit with the Miroir d'eau just south, an ornamental pond that gives a pleasing reflection of the castle walls.
2. Les Machines de l'Île
A gallery of mechanical animals in the Parc des Chantiers on the Île de Nantes. A guided tour circulates continuously, and you need to join it because the guides stir each animal into life and visitor movement is limited while they are in motion. The highlight is the Great Elephant, which stomps alongside the gallery spraying water.
Those over 13 can ride the elephant for an additional charge, but book in advance as seats are limited. Opening hours run Tuesday to Friday 10:00-18:00 and Saturday and Sunday 10:00-19:00, February to December. The Carrousel des Mondes Marins, 200 m west, is a three-level roundabout of underwater creatures in the same spirit.
3. Passage Pommeraye
An elegant shopping arcade built between 1840 and 1843, festooned with neo-classical statuary. It connects Rue de la Fosse with Rue Santeuil, which is 9.4 m higher, so the shops sit on three levels with a flight of stairs midway.
It is a short walk from Place du Commerce, the city-centre square with outdoor cafes and upscale shopping, off which lead Place Royale, Quai de la Fosse and Rue Crébillon. Pair the arcade with a wander through the Graslin district nearby.
4. Île Feydeau
Handsome 18th-century architecture on what was an islet in a north arm of the Loire, stabilised and enlarged in the 1720s and turned into prime real estate for shipowners and merchants. The river arm was infilled in the 1930s, but the district kept its unity of style and is still called an island.
The central street is pedestrianised and lined with cafes. Just north is Place du Bouffay, an elegant pedestrianised square laid out in the 1770s with plenty of outdoor cafes and bars, making the two a natural pairing for a late afternoon.
5. Musée des Beaux-Arts
A beautiful building of 1801 with an extensive permanent collection and temporary exhibitions. It has absorbed the Chapelle de l'Oratoire, a baroque chapel of 1655 now used as an exhibition space.
It stands on Rue Clémenceau and opens Wednesday and Friday to Monday 11:00-19:00, with a late Thursday opening until 21:00. The Chapelle Notre-Dame-de-l'Immaculée-Conception, from 1470, is in the block south of the museum on Rue Malherbe.
6. Jardin des Plantes
A bosky park just north of the railway station, bounded west by Rue Stanislas Baudry and east by Rue Frédéric Cailliaud. It is free to enter during daylight hours.
By its northeast corner is the back entrance to Bouteillerie cemetery, which has elaborate 19th-century ornaments and First World War graves in regimented rows. It makes an easy first stop if you arrive by train.
7. Le Maillé-Brézé
A T-47 destroyer commissioned in 1957 and named for a 17th-century admiral, moored on Quai de la Fosse as a museum. Her only battle action was in 1962 as a troop carrier against the OAS uprising in Algiers, and she retired in 1988.
Visits are by guided tour starting every 30 minutes and lasting 90 minutes. Hours are daily 14:00-15:00 from September to June, extended to 14:00-17:00 in July and August. Take the tram to Gare Maritime.
8. Musée Jules Verne
The novelist was born in Nantes in 1828, and shipping and the sea figured largely in his early life. This museum of his life and works opened in 1978 and was renovated in 2005, the centenary of his death. He never lived here, but it holds his original furniture and personal items.
It is at 3 Rue de l'Hermitage, open Wednesday to Friday and Sunday and Monday 14:00-18:00, and Saturday 10:00-12:00 and 14:00-18:00. The Planetarium at 8 Rue des Acadiens is next door, open Monday to Friday 10:00-12:30 and 13:30-18:00, and Saturday and Sunday 13:30-18:00.
9. Île de Versailles
An island in the River Erdre, 1 km north of the city centre, reached by Tram 2. The entire island is laid out as a Japanese garden and is a pleasant place to relax.
It works well as a quieter counterpoint to the busy riverside quarters, and the tram makes it straightforward to reach from the centre.
10. Basilique Saint-Nicolas
A granite neo-gothic basilica built between 1844 and 1869. The site forced it to be aligned north-south rather than oriented traditionally to the east. It was badly damaged by Allied bombing in 1943 and reconstruction took until 1974.
Just south is Place Royale, a pedestrianised square with an elaborate fountain, laid out from 1786 when the old city walls were demolished. It too was bombed and restored like-for-like after the war.
11. Théâtre Graslin and Cours Cambronne
The theatre is the centrepiece of the neoclassical Graslin district, laid out from 1780. Cours Cambronne just south is a strip of park lined by fine buildings.
The Muséum d'Histoire Naturelle at 12 Rue Voltaire, 150 m west of Place Graslin, holds a huge collection of minerals, fossils and stuffed animals plus live snakes, and opens Wednesday to Monday 10:00-18:00. The Galerie des Oubliés, 50 m south of the museum at 2 Rue de Bréa, has rotating exhibitions of 20th-century artists, open Tuesday to Thursday 14:00-19:00 and Friday and Saturday 14:00-18:00.
12. Jardin Extraordinaire
An exotic garden in a former quarry, with waterfalls cascading from its cliffs. It is open free from 09:00 to 18:00.
It sits on the Île de Nantes, the mid-river island consolidated from a string of islets in the 19th and 20th centuries, which is reached by any of its 13 access bridges and holds several of the sights in this list.
13. Grue Titan Grise
A large crane at the west tip of the Île de Nantes, painted grey so you do not confuse it with the yellow one further east. The former banana warehouse here has been turned into an art and event space.
It pairs naturally with the Grue Titan Jaune, which stands just west of the Carrousel des Mondes Marins, and with the rest of the Parc des Chantiers.
14. Église Sainte-Croix
Built from 1669 in classical style, with a richly decorated interior. The elaborate belfry and clocktower were added in 1860.
It is a short detour from the central shopping streets and worth a look for the interior if you are already walking between Place Royale and the Bouffay quarter.
15. Basilique Saint-Donatien-et-Saint-Rogatien
A neo-Romanesque church built between 1872 and 1889, named for two Christian martyrs of Nantes around 300 AD. The chapel and cemetery outside are much older. The basilica suffered a serious fire in 2015 but reopened in 2021.
It sits away from the main cluster of central sights, so treat it as a separate outing rather than something to fold into a walking loop.
If you only have one day
Morning: Start at the Château des ducs de Bretagne, arriving for the Tuesday-to-Sunday 10:00 opening, and walk the free courtyard, ramparts and garden before the museum. Cross to the Miroir d'eau for the reflection of the walls, then head north to Place Royale and the Basilique Saint-Nicolas, and continue to the Passage Pommeraye to see the arcade and its statuary.
Afternoon: Walk south into Île Feydeau for the 18th-century merchant streets, then stop at Place du Bouffay for a late lunch among the outdoor cafes. From there make your way to the Île de Nantes for Les Machines de l'Île, joining the guided tour, and continue west to the Carrousel des Mondes Marins and the Grue Titan Grise.
Evening: Return to the centre and finish at the Théâtre Graslin and the Cours Cambronne, or take Tram 2 north to the Île de Versailles for a quiet end to the day in the Japanese garden.
