On the concrete floor before the locked double doors is a text in German, Hebrew, and English, that points out the crime of the Holocaust and the estimated number of Austrian victims. In the centre is a Star of David. Engraved on the plinth on the two sides and back of the memorial are the names of those places where Austrian Jews were murdered during Nazi rule: Auschwitz, Bełżec, Bergen-Belsen, Brčko, Buchenwald, Chełmno, Dachau, Flossenbürg, Groß-Rosen, Gurs, Hartheim, Izbica, Jasenovac, Jungfernhof, Kaiserwald, Kielce, Kowno, Łagów, Litzmannstadt, Lublin, Majdanek, Maly Trostinec, Mauthausen, Minsk, Mittelbau/Dora, Modliborzyce, Natzweiler, Neuengamme, Nisko, Opatów, Opole, Ravensbrück, Rejowiec, Riga, Šabac, Sachsenhausen, Salaspils, San Sabba, Sobibor, Stutthof, Theresienstadt, Trawniki, Treblinka, Włodawa, and Zamość. The Holocaust Memorial is site specific and would be entirely different if it had been planned and constructed on a different site. Therefore, it is intricately connected with the history, institutions, and other works of art in Judenplatz. Judenplatz and the memorial are unique in Europe. The square unites the excavations of the medieval synagogue underground, that was burned down in the "Viennese Geserah" of 1420, with the modern memorial above ground. On the ground floor of the neighbouring Misrachi house, the "Dokumentationsarchiv des österreichischen Widerstandes" in co-operation with the Israelitische Kultusgemeinde Wien established an information area. Names and data of the 65,000 murdered Austrian Jews, and the circumstances that led to their persecution and murder, are publicly presented. The museum at the Judenplatz, which is in the Misrachi house, has a permanent exhibition about the history of Judenplatz, and the foundations of the destroyed Or-Sarua synagogue directly under the memorial can be visited.
