In the basement of the Nordstra;e 25 (previously: Judengasse 31, also: House „Der schwarze Bär“) was the Mikwe fünner. The moat of the medieval city defenses, in the course of which the street extends, was here überwwbt and a corresponding facility was established.

Although it is not an original "Jüdische place", the orphanage printing house is nevertheless important for the Jüdische history of Hanau. It stands in the direct tradition of the two "oriental printing houses". The typefaces and types of the Typographia Orientalis by Bashuysen were transferred to this printing house via several changes of ownership, in which Hebrew works were still occasionally printed.

The old Hebrew types of the predecessor printing house were used for the last time in the Orphanage Printing House in 1797.

In 1708, Heinrich Jakob Bashuysen, preacher of the Dutch congregation in Hanau and professor of oriental languages and church historyat the Hohe Landesschule in Hanau, established a new Oriental printing house. He used this printing house mainly to publish his own publications in the field of Oriental studies. This luminary in the field of Oriental studies initially worked closely with Jewish printers. However, he fell out with them. The dispute went all the way to the Reichshofrat in Vienna, where the files are still stored today.

In the 17th century, there was a prohibition in Frankfurt am Main according to which Jews were not allowed to own or run their own printing shops. Since there was nevertheless brisk trade in Hebrew books at Frankfurt fairs, Jewish printers either had to resort to other, Christian printing houses in Frankfurt, or move to surrounding cities where there was no prohibition of this kind. One of these "alternative cities" was Hanau.

After a mineral spring was discovered in Hanau in 1709, Wilhelm IX of Hanau had the Wilhelmsbad spa built in the 1760s and 1770s  The aim was to open the spa to all subjects - including Jewish bathers . Therefore, a separate pavilion was built for them. Offered were, in addition to their own rooms and bathing facilities, their own kosher kitchen.

From 1890, the Jewish Community House also housed the Jewish Community School. This was crucial to the development of the community, as the Jewish Community School allowed for an autonomous, Jewish education for children.

For a long time there was vehement resistance from the Hanau Vorsteheramt against an independent, Jewish school system. Officially, the aim was to bring the Jewish community closer to the Christian community and to put aside mutual prejudices. At the same time, however, one reason was that the "Jewish youth should give up a number of bad habits".

The Jewish Community House housed in the annex the mikvah (ritual bath). 

The Jewish community house, built in the 18th century and acquired by the Jewish community after the opening of the Hanau ghetto, was located on the property, as well as the Jewish community school since 1890. The community house itself played a decisive role. The fact that the community house was acquired was an important stage in the development of the community. It was a step from isolation in the ghetto to becoming an emancipated part of the urban community. But a community house also strengthens a community in other ways.
