The Hofburg is a former Habsburg palace in Innsbruck, and considered one of the three most significant cultural buildings in the country, along with the Hofburg Palace and Schönbrunn Palace in Vienna. The Hofburg is the main building of a large residential complex once used by the Habsburgs that still includes the Noblewomen's Collegiate Foundation, the Silver Chapel, the Hofkirche containing Emperor Maximilian's cenotaph and the Schwarzen Mandern, the Theological University, the Tyrolean Folk Art Museum, Innsbruck Cathedral, the Congress, and the Hofgarten (Court Garden).
The original Hofburg palace was constructed from several elements under Archduke Sigismund around 1460. This structure included sections of medieval fortifications that ran along the eastern city wall. The building incorporated the Rumer Gate, which was later converted into the Heraldic Tower in 1499 by Jörg Kölderer under Emperor Maximilian I. The palace was expanded several times during the next 250 years. Between 1754 and 1773, the Hofburg palace underwent two stages of Baroque structural changes under Empress Maria Theresia: the south tract was constructed (1754–1756) on the Hofgasse according to plans by J. M. Gumpp the Younger, and the main façade was added (1766–1773) on the Rennweg according to plans by C. J. Walter. During this period, the Giants' Hall was completed with ceiling frescoes by F. A. Maulbertsch, and the Imperial Chapel was built (1765) in the room where Maria Theresa's husband Emperor Francis I had died.
Today, the Hofburg contains five themed museum areas: Maria Theresa's Rooms from the eighteenth century, Empress Elisabeth's Apartment from the nineteenth century, a Furniture Museum, an Ancestral Gallery, and a Painting Gallery. These themed museum areas illustrate various aspects of the political and cultural history of the former imperial palace, which remained in the possession of the Habsburgs for more than 450 years.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
