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:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
