This was today, 75 years ago.
Because of this, there was a memorial service today at the Stadttempel in Vienna, which is the biggest synagogue in Austria.
President Fischer was there and held a speech and also the Austrian Supreme Rabbi Chaim Eisenberg and the IKG-leader Oskar Deutsch (leader of the Jewish Community in Austria).
The Stadttempel synagogue was the only one of over 100 synagogues in Vienna that was NOT burned to the ground 75 years ago, even though the interior was destroyed.
The reason why it was not burned down by the Nazis:
The synagogue was constructed in 1825 and 1826. The luxurious Stadttempel was fitted into a block of houses and hidden from plain view of the street, because of an edict issued by Emperor Joseph II that only Roman Catholic places of worship were allowed to be built with facades fronting directly on to public streets.
Ironically, this edict saved the synagogue from total destruction during the Kristallnacht in November 1938, since the synagogue could not be destroyed without setting on fire the buildings to which it was attached. The Stadttempel was the only synagogue in the city to survive World War II, as the Nazis destroyed all of the other synagogues and Jewish prayer-houses in Vienna.http://en.wikipedia.org/wiki/Stadttempel
