Château de Chaumont is a Renaissance fortress overlooking the Loire River in Chaumont-sur-Loire, inscribed on UNESCO's World Heritage List as part of the Loire Valley cultural landscape. Founded in the 10th century by Odo I, Count of Blois, the castle was destroyed by Louis XI but reconstructed between 1468 and 1566 by the d'Amboise family in Renaissance style, surrounding three sides of an ornamental courtyard. The castle hosted notable figures including Nostradamus, sculptor Nini, Benjamin Franklin, and Germaine de Staël during its distinguished history. Protected as a historical monument since 1840, the château has been state-owned since 1938 and welcomes over 500,000 visitors annually. The 32-hectare Domaine combines the castle, stables, landscaped park, and the International Garden Festival, functioning as a contemporary art and nature centre with rotating exhibitions by renowned photographers and artists throughout the year.
