Saint-Dizier (pronounced as /fr/) is a subprefecture of the Haute-Marne department in north-eastern France.[2]
It has a population of 23,382 (2018 figure) and is a subprefecture of the department. Although Saint-Dizier is marginally the most populous commune in Haute-Marne, the préfecture (capital) resides in the somewhat smaller commune of Chaumont.
Located approximately 120miles east of Paris, halfway to Strasbourg, it is five miles from Western Europe's largest man-made lake, Lake Der-Chantecoq.
The climate in Saint-Dizier is oceanic according to the Köppen climate classification (Cfb code). However, far from any ocean or sea, Saint-Dizier experiences continental climate characteristics resulting in cold winters with freezing nights and cool days with temperatures staying in the single digits and warm to hot summers with frequent thunderstorms.
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.
