The Château de Chaumont-sur-Loire is like a castle out of a fairytale. With its round defensive towers and imposingly tall walls, it is a castle that will transport you back to the Middle Ages.

The name Chaumont derives from the French “chauve mont“, meaning “bald hill.” Unlike some of the other Renaissance châteaux of the Loire Valley, the Château de Chaumont is much older and built for function rather than entertaining.

But Château de Chaumont-sur-Loire is perhaps most famous for the being the place Queen Catherine de Medici banished her husband’s mistress Diane de Poitiers after his death.

It is a few miles from the Loire river near other famous châteaux in the area like Château de Chenonceau, Château de Cheverny, Château de Chaumont, and Château de Chambord, near the cities of Amboise and Blois. It is about 3 hours away from Paris, making it ideal for a day trip from the city.

So let’s explore how the Château de Chaumont-sur-Loire came to be and what to see inside, shall we? Allons-y!


The first castle here was built by Odo I, Count of Blois, dating back to the 10th century. It stood on a tall hill looking down at the the river Loire, ready to protect the town of Chaumont.

In 1465, King Louis XI seized the Château from nobleman Pierre d’Amboise and ordered in razed as punishment for its owner’s rebellion against its rule. It was later rebuilt by Pierre’s son and grandson. This is mostly the castle we see today.

On March 31, 1550, Queen Catherine de Medici bought the castle from the Amboise family for the sum of 120,000 livres (the currency of the day).

The Château became famous when King Henri II died and Queen Catherine de Medicis forced her husband’s mistress Diane de Poitiers to move here instead and give up the Château de Chenonceau.

Chenonceau had been given to Diane as a gift, and Catherine did wait to seize it back as soon as she became regent on behalf of her underage son. Diane did not live here for long, and the château passed from her family to a variety of other hands.

It was eventually donated to the French government by the De Broglie family in 1938 and is today designated as a historic monument. The Loire Valley châteaux like Chaumont are officially recognized on the UNESCO world heritage list.
