Klobuk is a medieval fortress in Bosnia and Herzegovina. It is located on the karst plateau of Mirotinske grede, near the village of Klobuk, Trebinje, in the Republic of Srpska entity of Bosnia and Herzegovina. It is believed to have been built in the 9th century. In the work of Constantine Porphyrogenitus De Administrando Imperio in the middle of the 10th century, he mentions a town in the parish of Vrm in the county of Travunija. The fortress is also mentioned during the reign of archon Stefan Vojislav in the 11th century. The town of Klobuk was part of the state of Nemanjić until 1321, when this area passed into the hands of Bosnian rulers. It was first in the possession of the Sankovićs, and then from 1395 to 1442 in the possession of the Pavlovićs, who took it from Sankovićs. Then in 1442, it was taken over from Pavlović by Stjepan Vukčić Kosač sometime before 1442. During the 15th century, it was governed by a knyaz on behalf of the lord, and also had the castellan as a military commander.
The Ottomans captured Klobuk in 1477, and since then an Ottoman army crew has been stationed in the fortress until 1878, when they offered fierce resistance to Austro-Hungarian forces. The fortress gained importance after the Peace of Karlovac in 1699, when it became a prominent point towards the possessions of Venetia in Dalmatia and towards Montenegro. During the Ottomans, it belonged to the Sanjak of Herzegovina.
Inside Klobuk, in front of the former church, on the foundations of which the mosque was built, there is a stećak tombstone of the nobleman Vukosav Zemlić. Today, only towers up to 6 meters high are preserved, and some walls.

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.
