Origin and history
The Saint-Georges-d'Alschwiller is an archaeological vestige located in Soultz-Haut-Rhin, in the Haut-Rhin department. This site corresponds to the location of a missing village, Alschwiller, mentioned since 1135. The village housed a castle in 1289 and a chapel, which disappeared at the end of the 18th century. The village itself had already disappeared in the 14th century, leaving this motte as the only testimony of its existence.
The truncated structure of the moth was searched in 1857 by Max de Ring, revealing a "wall enclosure". These remains, though partial, attest to the strategic importance of the site in the Middle Ages. The motte was classified in the additional inventory of historical monuments by order of 22 November 1989, thus protecting all remains, including the soil.
The site is now owned by a private company. Its name, "Mont Saint-Georges", evokes a possible religious dedication or a local legend, although the available sources do not specify the exact origin of this appellation. The archives of the former bishopric of Basel and the documents of the Decapole (Saint Empire) mention Alschwiller between 1337 and 1357, confirming its integration into the administrative and religious networks of the time.
