In 1945 the Arsenal was heavily damaged by bombing, however after the war most it was rebuilt into its original form. In the following years, several new constructions, primarily in the south, were undertaken, such as the workshops for the State Theatres (1959 until 1963) and the rehearsal stage for the Burgtheater in the 1990s. From 1961 until 1963 the "Fernmeldezentralamt" and 1973 buildings for the "Post- und Telegraphendirektion für Wien, Niederösterreich und das Burgenland" (Mail and Telegraph Authority for Vienna, Lower Austria and Burgenland), today the "Technologiezentrum Arsenal" (Technology Centre Arsenal) of the Telekom Austria) with the 150-metre high Funkturm Arsenal.
