In 2000, the reorganisation of the Federal Building Construction Department culminated in the transfer of non-military state-owned properties from the Republic of Austria to the Federal Property Department Bundesimmobilien Ges m.b.H. (BIG). However, approximately 65 significant and unique historic buildings (e.g. Hofburg Vienna, Hofburg Innsbruck, Hohensalzburg Castle, Kunsthistorisches Museum, Vienna State Opera, Schönbrunn Zoo) remained within the public sector, as they constitute Austria's cultural heritage or have special significance for the Republic of Austria.
As a result of this reorganisation, the Burghauptmannschaft in Vienna, which was then renamed Burghauptmannschaft Österreich (BHÖ), took charge of a considerable number of objects and its scope of responsibility increased. In very general terms, the BHÖ is now responsible for property administration and construction management of all those objects and properties in Austria which are owned by the Republic and administered by the Federal Ministry of Economy and Labour.See more
