The wing of Festsaaltrakt was created as a part of the Imperial Forum project by Carl Hasenauer in 1866; in 1869, the plans were broadly modified by Gottfried Semper. It was constructed by Ludwig Baumann between 1910 and 1923.The large State Hall, spanning about 1,000 m2 and the Ceremonial Hall with marble everywhere are famous.

In 1958, the Congress Centre was established there and the OSCE has had its offices there since 1992.
 

In 2005 the so-called boiler house courtyard ("Kesselhaushof") was equipped with a roof and a conference hall (see press folder and downloads).
