Origin and history

The Hôtel du Breuil-de-Saint-Germain, located in Langres, is a mansion built in 1576 by Sébastien Valtier de Choiseul on a vast land acquired for this purpose. The building, transformed over the centuries, embodies architecture of the late Renaissance and 18th century. Its facades and roofs were classified as historical monuments in 1921, marking its heritage value.

In 1820, the property moved to the family Du Breuil de Saint-Germain, which retained it until 1923. That year, Madame du Breuil de Saint-Germain bequeathed the hotel to the Société historique et archéologique de Langres (SHAL), provided that she created a museum there. Unable to ensure its maintenance, the SHAL gave it in 2009 to the City of Langres, which launched a major restoration (2009–2013) for 1.3 million euros, co-financed by DRAC and patrons.

The works reveal a numismatic treasure (2,000 pieces of gold and silver) and Renaissance paintings on beams. Since 2013, the hotel has housed the Maison des Lumières Denis Diderot (MLDD), a museum dedicated to the Langarian philosopher and the Century of Lights. On 400 m2 and four floors, 250 objects explore his life, his work (including the Encyclopedia), and the intellectual context of the 18th century. The garden, designed by Louis Benech, and the museum by Atelier Akiko complete this cultural project.

The museum is structured around ten thematic rooms: the history of the building, Diderot's youth in Langres (born in 1713 in a family of cutlery), his Parisian journey, his travels (like that in Russia in 1773 to meet Catherine II), and his commitment to the arts and sciences. The Encyclopaedia, directed by Diderot and D-Alembert, occupies a central place, with focus on its design, detractors, and editorial impact (35 volumes, 1,000 workers involved).

The hotel also illustrates the links between Diderot and Langres: although it has never lived, the city celebrates its heritage through collections of cutlery (a tribute to its father, craftsman) and personal archives. Ranked Musée de France, the site combines architectural heritage, local memory and the influence of the Lumières' ideas.
