The Château de Chenonceau is a French château near the small village of Chenonceaux, in the Indre-et-Loire département of the Loire Valley in France.
The château was built on the site of an old mill on the River Cher, sometime before its first mention in writing in the 11th century. It was designed by the French Renaissance architect Philibert de l'Orme.
The original château was torched in 1412 to punish owner Jean Marques for an act of sedition. He rebuilt a château and fortified mill on the site in the 1430s. Subsequently, his indebted heir Pierre Marques sold the castle to Thomas Bohier Chamberlain for King Charles VIII of France in 1513 (this leads to 2013 being considered the 500th anniversary of the castle: MDXIII–MMXIII.) Bohier destroyed the castle, though its 15th-century keep was left standing, and built an entirely new residence between 1515 and 1521. The work was sometimes overseen by his wife Katherine Briçonnet, who delighted in hosting French nobility, including King Francis I on two occasions.
