In 1906, the Jewish community in Posen began building a new synagogue to replace old synagogues in Posen. It was completed in 1907 and quickly became a religious and cultural focal point for Jews in Posen. This changed rapidly when the Germans invaded Poland in September 1939. Already on September 9, the Germans closed the synagogue and in 1940 the star of David, which adorned its front, was taken down. The synagogue was looted and began to decay. Its dome and other embellishments were removed and it was only a matter of time before it would be demolished. But in 1941, the Nazi governor, Arthur Greiser, decided to build a swimming pool inside the synagogue, which was probably saved it from being destroyed. The swimming pool was completed in 1942 and was primarily for German soldiers and members of the Hitler Youth.

After the war, the communists kept the swimming pool and turned into a bath house. The Jewish population of Poznan was greatly reduced and its influence was weak and from the new communist rule there was no interest in restoring it. The swimming pool was in use until the mid-2000s when the synagogue was returned to Poznan’s Jewish community. In 2021 it was closed to the public and exactly what plans there were with the synagogue seemed unclear.
