The Vosges (French pronunciation: ​[voːʒ]) (German: Vogesen [voˈɡeːzn̩]), also called the Vosges Mountains, are a range of low mountains in eastern France, near its border with Germany. Together with the Palatine Forest to the north on the German side of the border, they form a single geomorphological unit and low mountain range of around 8,000 square kilometres (3,100 sq mi) in area, which runs in a north-northeast direction from the Burgundian Gate (the Belfort–Ronchamp–Lure line) to the Börrstadt Basin (the Winnweiler–Börrstadt–Göllheim line) and which forms the western boundary of the Upper Rhine Plain.
