Haut-Rhin
Haut-Rhin is a department in the Grand Est region, France, bordering both Germany and Switzerland. It is named after the river Rhine. Its name means Upper Rhine. Haut-Rhin is the smaller and less populated of the two departments of the former administrative Alsace region, the other being Bas-Rhin, especially after the 1871 cession of the southern territory known since 1922 as the Territoire de Belfort, although it is still rather densely populated compared to the rest of metropolitan France. It had a population of 767,083 in 2021.
On 1 January 2021, the départemental collectivities of Bas-Rhin and Haut-Rhin were merged into the European Collectivity of Alsace.
