The Old Town of Visoki was a medieval royal castle town built during the 14th century on the top of the hill overlooking town of Visoko, Bosnia and Herzegovina. The first mention of the town was on 1 September 1355, in the charter 'in castro nosto Visoka vocatum' written by Tvrtko I of Bosnia while he was a young ban. The town was abandoned before 1503, because it is not mentioned in the Turkish-Hungarian treaty from the mentioned year. In 1626, Đorđić mentioned Visoki among abandoned towns.
The Old Town of Visoki is at the top of Visočica hill, 213 metres high. Its position provides an excellent view at the plains below. The entry to the castle is on the southwest side, with two lookout towers. Passing through the entry you enter to a part that is called Podvisoki, i.e. to the town that was quite small, measuring 60 by 25 metres, and has signs and remains of early medieval houses. The thickness of the castle town walls is about 2 metres. Its position provides an excellent view at the plains below bordered by mountains Romanija, Jahorina, Treskavica and Bjelašnica in the east and southeast, Bitovnja in the south, the mountain Zec and Vranica in the Southeast, Vlašić in the west, and Tajan and Zvijezda in the north. The entry to the castle is on the southwest side, with two lookout towers.

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.
