The Imperial Chancellery Wing (Reichskanzleitrakt) initially housed the chancellery of the Holy Roman Empire. However, at the emperor's express wish Johann Emanuel Fischer von Erlach was commissioned with completing this wing in 1730.
Following the dissolution of the Holy Roman Empire in 1806, the chancellery was converted into residential suites for the imperial family.
From the middle of the 19th century they were occupied by Emperor Franz Joseph.
