The story that haunts this land
Vienna discovers in 1820 the Taborstraße, main artery of Leopoldstadt named after the Tabor church during the district's urbanization by Joseph II. This 1.5 km street with Biedermeier facades from 1830-1850 becomes the silent witness of the 1942 mass deportation: 50,000 Leopoldstadt residents are deported to death camps. You walk up this avenue where Yiddish, German and Hungarian once resonated, now marked by absence.
The Tempelgasse synagogue memorial, inaugurated in 1988, stands on the ruins of the synagogue destroyed during Kristallnacht on November 9-10, 1938. This synagogue built in 1870 could accommodate 2,200 worshippers at the heart of a 100,000-strong Jewish community. Joannis Avramidis' sculpture represents anonymous silhouettes, symbols of Holocaust victims. Here you measure the scope of destruction: a radiant place of worship reduced to a memorial.
Karmelitermarkt reveals its origins in the former Jewish ghetto authorized in 1678 under Leopold I. This 8,000 m² market with 85 permanent stands was nicknamed 'Mazze-Markt' before 1938, referring to unleavened bread for Jewish holidays. Nissim Atruel, Sephardic rabbi, led his community's settlement after the Spanish expulsion. You discover how this vibrant commercial place testifies to three centuries of Jewish presence in Leopoldstadt.
Augarten unfolds its 52 baroque hectares landscaped in 1715-1720 by Charles VI, Vienna's oldest park. Claudius Innocentius du Paquier founded there in 1719 the imperial porcelain manufactory, active until 1864. The two 51-meter flak-türme, anti-aircraft towers built in 1942-1945, brutally recall the war that decimated the Jewish community. You cross this park where baroque art mingles with Nazi scars.
Your journey ends at Morzinplatz, former seat of Vienna's Gestapo from 1938 to 1945 in the Metropole hotel demolished after the war. This sinister place saw 50,000 arrests and tortures during the Holocaust, near the Danube for executions. The 1989 memorial honors the victims. You carry away the memory of a district where 100,000 Jews built for two centuries a radiant European culture, before the 1938-1945 annihilation.
