After centuries of expulsion, Jews were allowed to settle in Erfurt again from 1809. With growing settlement, construction of the Small Synagogue as a community center for Erfurt Jews was begun in 1839 . The neoclassical style building was completed just one year later. Due to a strong growth of the congregation, the synagogue became too small after only 44 years and it was decided to build a new, larger synagogue.

Since 1799, the Jewish community in Boizenburg had a synagogue in the small Wallstraße. In 1864, the synagogue, which was originally a half-timbered building, was completely rebuilt and received a new brick facade. The consecration of the synagogue took place on October 1, 1864. The synagogue was sold as early as 1892 due to the decline in the number of congregation members. In 1934, the city took over the house and used it as a local museum until the 1980s.
