Hasegg Castle construction was completed soon after 1300, when Hall was rapidly becoming the center of Tyrolean commerce and salt mining. The building was originally erected to protect the salt mines, the shipping industry, the bridge across the river Inn and the old Roman Road. The castle's mint was established by Sigismund, Archduke of Austria in 1477. The first dollar-size silver coin was struck in 1486.
When Ferdinand II, Archduke of Austria had the old mint transferred from the Castle of Sparberegg to Hasegg in 1567, Hall experienced a decisive upswing. Between 1748 and 1768, Hasegg Castle became universally famous for its minting of silver Thalers of which it produced over 17 million specimens.
The mint ceased production in 1806 due to the Napoleonic Wars and the increasing lack of local silver resources.
The mint in Hasegg Castle is a museum now, and open to the general public. Demonstrations of historical minting techniques are given from time to time. The castle itself is an example of early Gothic era Tirolean fortress architecture. The pointed roof of the mint tower is of heavily tarnished copper.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.
