area north of Vienna was declared, at the Nazi-territorial reform of 15 October 1938 (see Greater-Vienna) to become the new 14th District, after which this district number was vacant by pooling of Rudolfsheim und Fünfhaus to the 15th District. By this redistricting, Hietzing had lost 94,000 of its 140,000 inhabitants from 1934. The magistrate for the 13th and 14th District is located in Hietzing currently. In 1938/1939, the Nazi regime set forth in a pheasant garden behind the Schlosspark of Schoenbrunn, started military construction, and built an SS barracks. It is now under the name of Maria Theresa Barracks, or Fasanengarten barracks, used by the armed forces. During the Second World War, the district showed much smaller bomb damage than other districts, since no major industries or major railway lines existed. After 1945 Vienna was taken in the Vienna Offensive of the Red Army on 13 April. From the autumn of 1945 to autumn 1955, Vienna was occupied by the four Allied powers and the 5th District was a part of the British sector - parades of the British army thus took place in the main courtyard of Schoenbrunn Palace, being used as their HQ. In 1952, key scenes were shot there of the Austrian film "1. April 2000" (director: Wolfgang Liebeneiner), in which the Austrian Government finally gets rid of the occupying powers in the year 2000. In the film, a spaceship lands in Ehrenhof, as thousands of people watched. The Lainzer Tiergarten became, through the 1938 territorial reform, part of the urban area. Hietzing became incorporated first in 1956, resulting in vastly larger surface area. Until then, it had belonged to the District Liesing. Since the late 1960s, the ORF operates, which by Roland Rainer designed and in 1975 completed ORF center Küniglberg, in which central TV and radio studios and directors and management of the public broadcaster are located. The name of the unassuming hill in the 13th District has since been used as a synonym for the ORF in the Austrian media discussion omnipresent. The building is, 40 years after its creation, renovated, and the financial problems of ORF were ridden about 2008, the headquarters of the institute to relocate. In 1997, at Rosenhügel (rose hill) in the area of Bertégasse und Wastlgasse, a slight modification was made to the border at the District Liesing, which mainly affected a small rural settlement.
