The Château de Langeais is a 15th-century Flamboyant Gothic castle in Indre-et-Loire, France, built on a promontory created by the small valley of the Roumer River at the opening to the Loire Valley. Founded in 992 by Fulk Nerra, Count of Anjou, the castle was soon attacked by Odo I, Count of Blois. After the unsuccessful attack, the now-ruined stone keep was built; it is one of the earliest datable stone examples of a keep. Between 994 and 996, the castle was besieged unsuccessfully twice more. During the conflict between the counts of Anjou and Blois, the castle changed hands several times, and in 1038 Fulk captured the castle again. After it was destroyed during the Hundred Years' War, King Louis XI (1461–1483) rebuilt Château de Langeais into what today is one of the best-known examples of late medieval architecture. It is especially noted for its monumental and highly decorated chimneypieces. Restored in the late 19th century, Château de Langeais came under the control of the Institut de France, who owns the site today. It is listed as a monument historique by the French Ministry of Culture and is open to the public.

The Museum of Maurice Dufresne (in French: Musée Maurice-Dufresne) is a technological history museum located in the mill at Marnay, near the Château of Azay-le-Rideau, France. It has acquired numerous important objects displayed in vast buildings containing some 25 rooms. The museum pieces are presented thematically: agricultural machines, silk and textile industries, musketry, hydraulic power, etc. Born in 1930, Maurice Dufresne began his training as a blacksmith at the age of fourteen and joined the "Compagnons du Devoir", an organization of journeymen -craftsmen, to begin a tour of France, working for twenty different employers. In 1958, he created his own company in Villeperdue in the region Indre-et-Loire. He started out in the salvage business and began saving things which he thought worthy of placing later in his museum, thereby avoiding the destruction of part of the French heritage. Thirty years later, on 24 October 1992, the prefect, the notables of the region and the press inaugurated the Museum Maurice Dufresne in Marnay near Azay-le-Rideau, on the banks of the Indre river in an old mill on a site owned by Geoffroy de l'Ile in 1026, which later became a paper factory in the time of Balzac. The scrap dealer from Villeperdue, armed only with his enthusiasm, was able to create this amazing museum of collections of machines from a road roller to a hearse, from a copper sulfate sprayer to a Louis Blériot monoplane, and to present all of this in enjoyable surroundings. His museum today presents more than 3,000 machines in warehouses covering 10,000 m2. It has already attracted 600,000 visitors and 23 guestbooks are filled with comments from around the world. In the last few years, Maurice Dufresne has continually travelled between Marnay and Villeperdue, where 27 people run the medium-sized salvage business.
