Žabljak Crnojevića is an abandoned medieval fortified town in Montenegro located on the confluence of the Morača river in Lake Skadar. It is believed that this fortress was founded in the 10th century during the reign of the Vojislavljević dynasty in then-known Dioclea, whereas the first known written testimony of the fortress originate from mid-15th century.
The fortress served as the capital of Zeta under the Crnojević dynasty from 1466 till 1478, being the seat of Stefan and Ivan Crnojević. However, Ivan Crnojević was forced to move the capital in 1478 when the Turks seized the town during the siege of Shkodra, holding it until the decision of the Berlin Congress in 1878 when it fell under Montenegrin administration once again after 400 years of Turkish rule.
The town has tall walls with towers, as well as one gate. Within the walls can be found Ivan Crnojević's court, Church of Saint George (was turned into a mosque during Ottoman rule), housing and military facilities, a warehouse for clothes and a water tank, most of which are preserved.
In the early 17th century, the town was under Turkish rule. The fortress had only one resident, the Dizdar Aga (Turkish official).

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.
