The village is located in the extreme southwest of Sundgau. It is at the confluence of the Largue, which crosses it, and the Grumbach. It is more or less equidistant from Mulhouse to the north, Belfort to the southwest and Basel to the east. It borders the neighboring village of Seppois-le-Bas.
History
Seppois-le-Bas was hard hit during the conflicts of the First World War. The commune was decorated on November 2, 1921 with the Croix de Guerre 1914-1918.
Economy
Despite its location near the “automotive of the future” competitiveness cluster (Mulhouse, Belfort, Sochaux-Montbéliard) and the Basel site in full economic expansion, the village remains largely rural.
Demography
In 2019, the town had 507 inhabitants, an increase of 4.75% compared to 2013 (Haut-Rhin: +1.1%, France excluding Mayotte: +2.17%).
Places and monuments
The Sainte-Croix chapel, erected in the middle of the village. Mentioned for the first time in 1620, it is certainly older because it has a choir in Gothic architecture with a semicircular vault; converted into a socio-cultural center, exhibitions and conferences are held there regularly;
The Saint-Hubert church, destroyed during the First World War and rebuilt in 1928. It replaced the first church of 1859; you can see remarkable sculptures and paintings (stations of the cross, communion bench, high altar, paintings representing Saint Sebastian and Saint Roch) and its organ by Frédéric Haerpfer; beautiful fountains, spread over the main axis;
Memorials:
The monument to the shots of Ballersdorf;
The felled Kreuzengarten lime tree, located in the garden of the old Sainte-Croix chapel, was several hundred years old.
