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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
