The DC Towers, also known as the Donau City Towers, is a mixed-use skyscraper complex in the Donaustadt District of Vienna, Austria. The towers were designed by French architect Dominique Perrault. Werner Sobek AG was responsible for the structural engineering as well as the facade and height access planning of DC Tower 1.
DC Tower 1, the tallest skyscraper in Austria at 220 metres (720 ft) or 250 metres (820 ft) including the antenna spire, was officially finished with an opening ceremony on 26 February 2014 attended by architect Perrault and former astronaut Buzz Aldrin. Due to the 2008 financial crisis, ground breaking was delayed several times. Eventually, construction was started on 17 June 2010.
