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: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.
