The Dukes of Brittany Castle
The Castle of the Dukes of Brittany, with its interior and surroundings, is definitely worth a visit. It has been beautifully refurbished. A walk through the gardens will also provide a nice view of the monuments, like the Cathedral or The LU Tower, for example. If you have time, you can also enter the Nantes History Museum, which is a very modernist museum.
