Chantilly, Oise in the context of "Musée Condé"

The Très Riches Heures du Duc de Berry (French pronunciation: [tʁɛ ʁiʃz‿œʁ dy dyk də beʁi]; English: The Very Rich Hours of the Duke of Berry), or Très Riches Heures, is an illuminated manuscript that was created between c. 1412 and 1416. It is a book of hours, which is a Christian devotional book and a collection of prayers said at canonical hours. The manuscript was created for John, Duke of Berry, the brother of King Charles V of France, by Limbourg brothers Paul, Johan and Herman. The book is now MS 65 in the Musée Condé, Chantilly, France.

Consisting of a total of 206 leaves of very fine quality parchment, 30 cm (12 in) in height by 21.5 cm (8+1⁄2 in) in width, the manuscript contains 66 large miniatures and 65 small. The design of the book, which is long and complex, has undergone many changes and reversals. Many artists contributed to its miniatures, calligraphy, initials, and marginal decorations, but determining their precise number and identity remains a matter of debate. Painted largely by artists from the Low Countries, often using rare and costly pigments and gold, and with an unusually large number of illustrations, the book is one of the most lavish late medieval illuminated manuscripts. The work was created in the late artistic phase of the International Gothic style.

The Château de Chantilly (pronounced [ʃɑto d(ə) ʃɑ̃tiji]) is a historic French château located in the town of Chantilly, Oise, about 50 kilometres (30 miles) north of Paris. The site comprises two attached buildings: the Petit Château, built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. The château is owned by the Institut de France, which received it from Henri d'Orléans, Duke of Aumale.

A historic monument since 1988, it is open to the public. The château's art gallery, the Musée Condé, houses one of France's finest collections of paintings. It specialises in French paintings and book illuminations of the 15th and 16th centuries.

The Chantilly Conferences were a series of three conferences held between 1915 and 1916 by the Allied Powers of World War I. The conferences were named after Chantilly, France, where the meetings took place.
