The Château de Chenonceau is a French château spanning the River Cher, in France. It is one of the best-known châteaux of the Loire valley. 

A château is a manor house or residence of the lord of the manor or a country house of nobility or gentry, with or without fortifications, originally - and still most frequently - in French-speaking regions.

The history of the Château de Chenonceau is defined by an almost uninterrupted succession of women who built, embellished, protected, restored and saved it. The first château was a medieval château dating from the 12th and 13th centuries, of which only the dungeon remains: the Tour des Marques. The current château was built in 1514-1522 on the foundations of an old mill and was later extended to span the river. 

The bridge over the river was built 1556-1559 and the gallery on the bridge, was built 1570-1576.  An architectural mixture of late Gothic and early Renaissance, Château de Chenonceau and its gardens are open to the public. Other than the Royal Palace of Versailles, it is the most visited château in France.
