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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
