Château de Azay-le-Rideau in the Loire Valley, France, is a former feudal castle. During the 12th century, the local seigneur Ridel d’Azay, a knight in the service of Philip II Augustus, built the fortress to protect the Tours to Chinon road.
Palace of Versailles. One of France's most visited tourist sites, the chateau de Versailles west of Paris has been undergoing renovation work since 2003 when the government launched a old "Grand Versailles" project to restore it to full former glory.
The abandoned Château de Carnelle was designed for André Philippe Alfred Regnier, Duke of Massa, in 1875 by renowned architect Hippolyte Destailleur. It is located on the edge of the forest Carnelle, in the Île-de-France region of France. This land was originally given to the monks of Saint-Denis by Charles V; eventually, the Duke of Massa, childless, donated his estate to the city of Paris and it was converted into a sanatorium in 1930. The castle was finally closed in 1992.
Chambord Castle, France. Given that Chambord was, officially, built to serve only as a hunting lodge, it is quite an impressive construction. It is also worth a mention that the location of the castle was chosen by King François I as he desired to be near his mistress, Claude Rohan, whose palace was located adjacently. The massive castle has 440 rooms, 365 fireplaces, and 84 staircases, and it is the largest chateaux in the Loire Valley in France.
