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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
