Zvornik is a medieval castle located in Zvornik, Bosnia and Herzegovina, on the mountain Mlađevac overlooking Drina Valley.
The medieval town of Zvornik called 'Đurđevgrad' or 'Kula Grad' was first mentioned as a property of Bosnian medieval feudal family Zlatonosović in 1410 when Hungarian King Sigismund was in the area. It was probably built in the 12th or 13th century and is one of the largest medieval fortresses in Bosnia and Herzegovina.
Part of the structure was destroyed in 1878 during the Austro-Hungarian invasion of Bosnia and Herzegovina.
Ustasha troops of the fascist Independent State of Croatia occupied the fortress along with the rest of Zvornik and most of Bosnia, in April 1941. The fortress was liberated in July 1943 by the 1st Proletarian Brigade during the Battle of Zvornik.
Beginning on 8 April 1992, about 300 soldiers of the Army of the Republic of Bosnia and Herzegovina defended the fortress from Serb soldiers of the Yugoslav People's Army during the first stages of the Bosnian War. Following the Bosnian War, Zvornik became a part of Republika Srpska and the new Serb government had a church built on the grounds of the fortress and relocated a church bell from the village of Divič to the new church to mark their victory over Bosniaks.
In May 2013, the remains of several war victims from the 1990s conflict were uncovered in Kula grad.

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.
