The building was originally built in 1916 – 18 by the Evangelical Ecclesiastical Benevolent Society ( '' Evangelisch Kirchlichen Hilfsverein '' ) or EKH . After the Potsdam Conference in August 1945 about 100 houses in the '' Nauener Vorstadt '' quarter , which bordered on the New Garden , were cordoned off and renamed as Military Camp No. 7 ( '' Militärstädtchen No. 7 '' ) . In this area were located the command centre of the KGB for Germany , which was housed in the former boarding school attended by Empress Augusta Victoria . The neighbouring building of the women 's benevolent society ( '' Leistikowstraße 1 '' , previously '' Mirbachstraße 1 '' ) was used as the counter-intelligence detention centre
