It is not known whether there was already a prayer hall or a synagogue in the Middle Ages.

In the second half of the 17th century (before 1671) a synagogue was built at the Obertor (Obertorstraße 33). It was a half-timbered building with a hall storey, gable roof, crippled hipped roofs and six large round-arched windows 3.40 meters high. In 1837, the building was rebuilt and a women's gallery was added to the upper floor. Until 1895, this synagogue was used.
