Middachten Castle was first time mentioned in 1190, owned by Jacobus de Mithdac. Early in the 14th century Everardus van Steenre transferred its ownership to Reinald, count of Gelre. Everardus then got the castle back as a loan in 1357. The castle would remain with this family until 1625. During this time the castle was destroyed and rebuild several times. In 1673 Stadtholder William III conquered the city of Bonn, making the occupying French troops retreat, who destroyed the castle. Godard van Reede and his spouse Ursula van Raesfelt then had the castle rebuild, based on the example of Het Loo Palace in Apeldoorn. It was designed by Jacobus Roman (1640-1716) and Steven Vennecool (1657-1719).
After the castle was rebuilt in 1698 a garden was built, based on the garden in Versailles in the period 1700-1725. In the late 18th century British style gardens became fashion, and the gardens were redone in this style. In 1900 count and countessa Bentinck-Van Heeckeren of Wassenaer had the gardens partially rebuilt in the original style by Hugo Poortman (a student of French garden artist Édouard André).
The castle used to have an extensive estate. However these are no longer owned by the owners of the castle. Buildings that used to belong to the castle estate can be recognized by the red and white coloring, for example the Post office in De Steeg.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.
