Khal Adas Yisroel, usually referred to as the Schiff Shul, was the main Orthodox synagogue in Vienna prior to the Holocaust. The synagogue no longer exists since it was destroyed by the Nazis on Kristallnacht . A building that was adjacent to the Schiffshul and was part its complex remains. A small shul currently exists in this building that is called Bet Hamidrasch Khal Chassidim and is led by Rabbi Avraham Yona Schwartz. There is also a memorial plaque at this site that states "This Jewish place of worship was destroyed by the Nazis in the pogrom of November 1938."
