Chateau Royal d'Amboise
The Chateau d'Amboise was a royal palace from the mid 15th to mid 16th century. King Charles VIII was born here in 1470. He also died here in 1498, when he bumped his forehead on a door frame on his way to watch a game of tennis.
These are working fireplaces!!!
Leonardo da Vinci is buried in the St. Hubert Chapel on the terrace of the chateau.
16th century battle armour. The Emir of Algiers (Algeria), Abd el-Kader was kept under house arrest in this chateau after he surrendered to France in 1843.
The Chateau d'Amboise is not the biggest, nor is the prettiest chateau in the Loire Valley, but it is a definite must see. You can't help but get immersed in its history.
Chateau de Chaumont-sur-Loire
Charles II built this between 1454 and 1510. When Henri II died, his wife Catherine de Medici forced Diane de Poitiers to exchange Chenonceau (see Day 3) for this chateau.

The luxurious stables of this chateau housed purebred horses in the 19th century.
Chateau de Chambord
The largest chateau in the Loire Valley. King Francois I commissioned this chateau in 1519, originally intended as a hunting lodge. It is over 500 feet long and 183 feet tall, has 77 staircases, 282 fireplaces and 426 rooms. The Chambord estate covers over 13000 acres and is surrounded by a 20 mile wall with 6 gates. It is the largest enclosed forest park in Europe. The chateau is so big and in the middle of nowhere, so the Louvre stored its most precious paintings (including the Mona Lisa) here during WWII.

The double spiral staircase in the center of the keep. Two concentric spirals wind independently, so two people never meet each other if they each take a different staircase. It is presumed that Leonardo da Vinci inspired this staircase. Also on display are saddles from the late 1800s, made by Hermes.
Chateau Royal de Blois
Each of the four wings of this chateau correspond to four distinct periods and style: Gothic, Flamboyant, Renaissance and Classicism. Both Francois I and Henri III lived here. Catherine de Medici died here on January 5, 1589.
Chateau de Cheverny

Alex grew up reading the Tintin comic books. The Chateau de Cheverny was the inspiration for Capitaine Haddock's mansion.
