Roonstrasse Synagogue, located in Cologne, Germany, is one of the five pre-Nazi synagogues of the locality, which was destroyed on November 9, 1938 during nation-wide attacks on Jewish-owned property (Kristallnacht) when Germany was under Nazi rule. The synagogue was subsequently rebuilt during the 1950s. It is currently a center of Jewish community of Cologne, and consists of a community center, a small display of items associated with Cologne Jewry, and a kosher restaurant. The interior of the reconstructed synagogue has a vast blue dome.
On August 19, 2005, Pope Benedict XVI visited Roonstrasse Synagogue. This visit was the second ever visit to any synagogue by any one of the Popes. There, he condemned nazism and antisemitism.
