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:
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
