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:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
