The city bears the name of Bagnos (“small bath”) which will be completed in Baigneux-les-Juifs following the arrival of many Jews in this new agglomeration.

The Jewish presence seems to date from the 13th century. The medieval synagogue was located  rue Vergier-au-Duc .

However, as in many other places in France in the end of the Middle Ages, the Jews were expelled from the city.
