Over the course of seven centuries, the Viennese Hofburg has been growing section by section to its current extent. Initially, constructed as a part of the Viennese city fortification, reconstruction work turned the castle into an imperial residence, when the Habsburg family came to power at the end of the 13th century. Until the 19th century, extension works followed and led to the Imperial Palace’s extent of 18 sections, 19 courtyards and 2.600 rooms, in which approx. 5.000 people are still working, even today.
Nowadays, the Viennese Hofburg is used under the flag of democracy, whereby its palatially rooms not only serve the Austrian Federal President as official residence, also they act as an appropriate setting for cultural services like, museums, congresses, fairs and exhibitions, banquets, ball nights and concerts.
According to the Viennese ball tradition, each year, this very particular charm of the Imperial Palace is used by the student union at BOKU (ÖH BOKU) to invite in association with BOKU’s rectorate to a splendid ball night, the so called BOKU Ball. Therefore, all the night through the Hofburg belongs to friends of the University of Natural Resources and Life Science, who then reanimate the Imperial Palace’s walls once more.
