The first written document of castle in Linz dates from 799 AD, during the reign of Charlemagne. Today there are still some walls of this castle, together with bastions and the Friedrich Gate, named after Emperor Friedrich III, who resided here until his death in 1493. As the temporary heart of the Habsburg Empire, Linz was raised by the Emperor to the status of provincial capital. In the 17th century, Rudolf II rebuilt the castle, which today is home to the Upper Austrian provincial Museum.
The south wing was destroyed in the City Fire of 1800, and was rebuilt in modern glass-and-steel architecture for the Capital of Culture year 2009. It now constitute the largest universal museum in Austria. The wings of Linz Castle contain the history of culture collections of the Upper Austrian Provincial Museum. The permanent exhibitions present a walk through the artistic and cultural history of Upper Austria from the Neolithic Age up to the 20th century. The new South Wing contains the permanent exhibitions on nature and technology in Upper Austria. There is a continuous programme of special exhibitions.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
