Château des ducs de Bretagne

Very well worth going. The chateau is very pretty, courtyard is big and there is plenty of space for sitting down and relax. The museum itself is top notch designed and very easy to walk around with clear signs and displays are nicely categorized. Combining with different ways of presenting: videos, games, 3D virtual screens, cartoon story telling, many other ways of references. Great for kids to visit. One of the best museums to visit, I didn’t feel bored at all during the 2 hours. The content of the museum is very educational, you get a full picture of the history of Nantes. And it’s not afraid of showing the “ugly” part of the history about salve trading. Some rare findings about WWII as well.

A nice castle with an insightful museum (need to buy tickets), visiting the castle is free however. The walk around the castle wall is very enjoyable, also around the moat with the ducks swimming around. Many people having picnics around the castle as well. There are many shops and cafes / restaurants around the beautiful streets outside the castle. You can easily spend at least half a day in the vicinity.

A great visit. Walked the ramparts and the moat for free. Information boards throughout giving an insight into the history of each area. Amazing views of the city and surrounding areas. There's secure bike parking,a cafe and toilets. Well worth a visit.

If Nantes, the Chateau is a must, really good location. Fantastic that you can walk around the outside/ramparts for free. It is amazing and such a nice vibe when walking around here.

Nice chateau with an elegant building that houses a museum. The castle was primarily built at the end of the 15th century by Francis Ii, the last Duke of Bretagne. I had expected more of that time, and the signing of the Edict of Nantes of 1598 signed by Henry IV. The museum is the Nantes' history museum, and you are guided through the centuries of the towns existence. All the texts are in French, so when you don't master that language, you will have to do with the visual impressions

Had a very quick visit. You even can go through the gates for free and make some pictures. Part of the so called 'Green Line'. If you want more you can pay to go inside the castle itself

A must see if you come to Nantes. They have a guided visit in English too. The outdoor of castel is free and open to the public, so are the rempars. But you must pay to visit the inside.

Very interesting museum about the history of Nantes and the area. Very modern and accessible with lifts to every exhibition room and even to the walls around! Highly recommended to visit it if you are in the area.
