In 1895, Archduke Friedrich created a suite of seven rooms as a residence for the Spanish royal family. His sister, Maria Christine (1858-1929), was the widow of Spanish King Alfonso XII, who had died in 1885 while she was pregnant with their only son, Alfonso XIII.
She lived in the Spanish Apartments until 1918, and Alfonso XIII stayed here on his frequent visits to Vienna. Only two rooms survived bomb damage at the end of World War II, the Small Apartment and the Large Apartment. Today they feature the original furnishings by Joseph Danhauser.
