One of the most famous and visited castles in France. It is unusual by the fact that it is located entirely on the river. The castle is about 500 years old. Château de Chenonceau has many well preserved interiors, so it is very interesting not only outside but inside as well. Not many people know, but it is privately owned, and thus turned into a museum and is opened to public.
If you like old castles, I strongly recommend you to go by car through the Loire Valley in France. There is a huge number of ancient castles located just 20 minutes drive from each other, or even less. I am sure you will love it!
Château de Chenonceau was preserved from destroying during the French Revolution, only because it was used as a bridge to cross the river, being the only one within many miles.
