Château de Nemours stands as one of the few intact medieval urban fortresses in Île-de-France, built around 1120 by royal chamberlain Gauthier Iᵉʳ de Villebéon and perched above the Loing river for over 800 years. Transformed in the 15th and 17th centuries by successive nobles, the castle was restored by local artists beginning in 1901 to establish its museum. Today it houses approximately 20,000 works spanning Gallo-Roman and Merovingian archaeology, religious sculptures, popular arts, and a notable collection of graphic arts, paintings, and sculptures from the late 19th and early 20th centuries.
