Innsbruck's old Court Palace, the Hofburg - a former imperial residence originally built in the 15th and 16th centuries - was remodeled in Baroque and Rococo style in the 18th century upon instructions from Empress Maria Theresa.
The palace is best viewed on a guided tour (available in English), which includes its luxurious apartments with their fine painted ceilings.
Particularly memorable is the Giant Hall (Riesensaal), a grand hall in polished marble and decorated in white and gold, with three large ceiling frescos from 1775 and fine portraits of the Imperial family.
