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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
