[1][2] 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).
During this period, the Giants' Hall was completed with ceiling frescoes by Franz Anton Maulbertsch, and the Imperial Chapel was built (1765) in the room where Maria Theresa's husband Emperor Francis I had died.
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.
In the fourteenth century, when Innsbruck was ruled by the House of Gorizia, the city's defensive walls included a section located where the Hofburg main façade stands today on Rennweg.
Frederick moved the seat of rule from Meran in present-day South Tyrol to Innsbruck, and constructed his New Residence, the building with the Goldenes Dachl west of the Hofburg area.
Sigismund expanded the Hofburg area through the acquisition of several houses on Hofgasse and various garden properties near the present-day cathedral.
[1] In 1495, the palace was extended to the north of the building complex and was used as the residence of Maximilian's second wife Bianca Maria Sforza, whose dowry may have financed the work.
[1] Maximilian's court master builder at the time was Nikolaus Thüring the Elder, who also built the Goldenes Dachl.
Ferdinand brought in Italian architect Lucius de Spaciis to redesign the Hofburg east wing (along Rennweg) and create a new banquet hall.
[1] The transformation of the Hofburg from a Gothic palace to a Renaissance castle was continued under Ferdinand II, Archduke of Austria (1529–1595), who brought in master builder Giovanni Lucchese to produce the renovations in the Italian style.
[1] During the seventeenth century, plans for further renovation under Leopold V, Archduke of Austria (1586–1632) and his successors were postponed because of the Thirty Years' War.
The first phase began with the submission of plans in 1754 by Johann Martin Gumpp the Younger,[5] who was commissioned to create new offices in the south wing (along Hofgasse), add a large central staircase, standardize the floor levels and room heights, and remove narrow stairs and unnecessary walls to produce comfortable rooms with uniform flooring and evenly-spaced windows.
[6] For Maria Theresa, the Hofburg took on greater importance "as a memorial site and representational building" to honor her husband.
New ceilings were installed, court building director Constantin Johann Walter was named creative planner, and in 1767 Maria Theresa placed her court architect Nikolaus Pacassi—responsible for converting Schönbrunn Palace into a residential palace in Rococo style—in charge of the design and appearance of the main façade on Rennweg.
[1] After the roof framework was modified in 1774, the Giants' Hall ceiling fresco was executed by Franz Anton Maulbertsch, the master of Austrian Rococo, between 1775 and 1776.
Vienna court sculptor August La Vigne was commissioned to design the residential area in the Rococo style.
[1] Since the Baroque reconstruction, the courtyard has been decorated with sculptural elements such as pilaster, frames, cornices and the cartouches with the Austrian striped shield in the gables of the facades.
