Château de Chinon was founded by Theobald I, Count of Blois. In the 11th century the castle became the property of the counts of Anjou. In 1156 Henry II of England, a member of the House of Anjou, took the castle from his brother Geoffrey after he had rebelled for a second time. Henry favoured the Château de Chinon as a residence: most of the standing structure can be attributed to his reign and he died there in 1189.
Early in the 13th century, King Philip II of France harassed the English lands in France and in 1205 he captured Chinon after a siege that lasted several months, after which the castle remained under French control. When King Philip IV accused the Knights Templar of heresy during the first decade of the 14th century, several leading members of the order were imprisoned there.
Used by Charles VII in the 15th century, the Château de Chinon became a prison in the second half of the 16th century, but then fell out of use and was left to decay. It has been recognised as a monument historique by the French Ministry of Culture since 1840. The castle, which contains a museum, is now owned and managed by the Indre-et-Loire General Council and is a major tourist attraction. In the early 21st century it was restored at a cost of 14.5 million euros.
The castle is divided, along its length, into three enclosures, each separated by a deep dry moat. There are some similarities with Château Gaillard, built by Richard the Lionheart in the closing years of the 12th century, which also consists of three three enclosures and sits on a promontory above a nearby town.References:
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
