The earliest data regarding human settlement at Vallimäe in Rakvere come from the Viking Age, an arrowhead from the 9th century and some broken pieces of pottery from this period have been found on the territory of the castle. There is more information about the last centuries of the prehistoric age when an ancient wooden stronghold surrounded by a fence stood in the place of the present convent building.
First written records about the stronghold called Tarvanpea come from the year 1226. In the middle of the 13th century the Danes started to replace the wooden stronghold with a more modern stone fortress.
After Virumaa and Harjumaa passed into the possession of the Livonian Order in 1347, a grand-scale reconstruction of the castle was carried out in several stages. In the first half of the 16th century a convent-type castle with a rectangular main tower was completed, it had strong flanks, a large front yard and an eastern gate consisting of several parts: the outer gate included a pitfall and a drawbridge and the inner gate had a lowered lattice. Living quarters and outbuildings were located in the front yard, near the circular wall.
During the Livonian war (1558–1583) the castle was attacked and damaged by the Russians, but it ended up under Swedish control. From 1602 to 1605 Rakvere fortress fell under the control of the Polish-Lithuanian commonwealth. When they retreated from Rakvere in 1605 during the war with Sweden, they blew up the castle.
Today Rakvere castle is open to the public. In addition to the museum you can taste knights’ favourite drink, a Malvasia wine, made after the oldest recipe at the wine cellar.
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.
