Moret-sur-Loing has two sides. A fortified town and royal residence, Moret-sur-Loing was long a frontier town between old France and Burgundy. This charming medieval city gently washed by the Loing was a magnificent source of inspiration for Monet, Renoir and Sisley. Before Fontainebleau, Moret-sur-Loing was one of the most important royal cities of medieval times. It kept the character of a fortified town until the nineteenth century. Its rich and surprising medieval past is evoked by the house of Francis I, the Renaissance gallery, the Porte Samois, the donjon, the old bridge, the museum recounting the History of the Nuns and Barley Sugar.
