The Dresden Synagogue or Semper Synagogue, today also called Old Synagogue was the synagogue of the Jewish community in Dresden, inaugurated in 1840 and destroyed in the November pogrom in 1938. The neo-Romanesque building designed by Gottfried Semper was the first modern synagogue to be uniformly designed inside in orientalizing style and served mainly Edwin Oppler as a model for numerous other synagogue buildings.

From the remains of the synagogue entrance, removed in 1984, a memorial in the form of a reconstruction of a portal has been created on the east side of the Great Berlin. Last use: residential development, in addition, the square received the nickname Jerusalemer Platz.

On the basis of a donation by the Halberstadt court factor Berend Lehmann (1661-1730), the magnificently furnished Baroque synagogue of the Halberstadt community was inaugurated in 1712, in the backyard area of Judenstraße 24-27 (on the site of two previous buildings). In contrast to the first public synagogue in the Prussian royal city of Berlin (1714), the Halberstadt house of worship visibly towered over the surrounding buildings from afar. As the first synagogue in Germany, it followed the architecture of its time.
