Memorial plaque Johann Plocek

At the Plocekhof in Denisgasse 54, the City of Vienna installed a memorial plaque in 1949 in honor of the namesake of the residential complex, Johann Plocek. The locksmith Johann Plocek belonged to a resistance group at the tramway depot in Brigittenau under the National Socialist regime. In January 1942, the Gestapo arrested him for investigative purposes. He was sentenced to death by the People's Court on December 8, 1942, for "preparation for high treason," and executed on March 30, 1943, at the Provincial Court in Vienna.
