Memorial plaque for victims of NS terror at the former site of SS, SD and Gestapo

In the year 2004, a memorial plaque was installed on the façade of the Theater Akzent in Theresianumgasse 16–18, the seat of the Vienna Workers' Chamber, dedicated to the victims of the national socialist regime. The memorial plaque recalls the formerly located Palais Alphonse Rothschild, which during the National Socialism served as the seat of the SS, the Security Service of the SS (SD), and the Secret State Police (Gestapo). The memorial plaque shows a fragmentary, cut-out text on a mirror and a factual explanation on glass. It was designed by Ingeborg Kumpfmüller. The memorial installation also includes a ball with a mirrored surface, located in immediate proximity to the plaque on the floor. The plaque replaced an older memorial plaque removed in the foyer in 1988
