During the Second Margrave War in 1552, Forchheim was occupied by troops of Margrave of Culmbach and later expanded with new fortifications. The town's defenses were improved with bastions, towers, and gates. During the Thirty Years' War, Forchheim served as a strategic location and a refuge, and its fortifications were further developed. Various outworks and defensive structures were added, designed by prominent architects. In the 18th century, additional buildings were constructed in the town center. After changes in ownership, the fortress lost its military importance and was gradually demolished starting in 1875. However, the moats were transformed into a park for public enjoyment.
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.
