The Château d'Oiron has its origins in the 15th century war with the English for control of France when a victorious Charles VII of France gave the domain and great forest of Oiron to Guillaume Gouffier who became governor of Touraine.
Guillaume Gouffier built a magnificent château and his offspring updated and improved it. In 1538, his daughter-in-law, Helene de Hengest, was responsible for the construction of a collegiate church adjacent to the château. In 1551, Henry II and his entire court were guests of Claude Gouffier who had been granted the title Marquis de Caravaz. Claude Gouffier served as the model for Charles Perrault's 'Marquis de Carabas' in his story, Puss in Boots.
Two generations later, another Gouffier was exiled from the king's court by Cardinal Richelieu in 1620. In the mid 17th century, Charlotte Gouffier became enamored with the renowned intellect, Blaise Pascal (1623–62), who spent considerable time at the Château d'Oiron. After Pascal died, Charlotte Gouffier married Francois d'Aubusson, the duc de La Feuillade, who enhanced the castle with his wealth and connections to Louis XIV. With the renovations, the castle ended up with a main building and two long projecting wings, one of which is a Renaissance structure built over a cloister. One of the galleries contains one of the most prestigious works of art from the French Renaissance period.
The Duc de La Feuillade's son sold the château to Louis XIV's mistress, Madame de Montespan who lived there for the rest of her life. Her son had little interest in the property as he preferred to be much closer to the royal court so in 1736 he sold the château to the Duc de Villeroi. After that, the château went into severe decline and in 1793 was ransacked by Revolutionaries. For many years the château lay abandoned until the government of France took possession just before World War II eventually converting it to a museum.
Recognized worldwide, the museum is dedicated to contemporary art.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
