Geography
Located approximately 120 mi east of Paris, halfway to Strasbourg, it is five miles from Western Europe's largest man-made lake, Lake Der-Chantecoq.

History
Named after an unknown saint (possibly Desiderius of Fontenelle), the town originated as a fortified settlement around a thirteenth-century château, eventually becoming a royal fortress to guard the French kingdom's eastern approaches. The town was besieged and captured by Charles V, Holy Roman Emperor, in the summer of 1544. A fire in 1775 destroyed two-thirds of the town center. The château was owned by the Orléans family until the French Revolution, was a base for German troops during World War II, and currently houses the Municipal Museum.
