The Citadel (Fellegvár) and the Lower Castle The Visegrád double castle system is one of the castles built by Béla IV recognizing the consequences of the Mongol invasion. The fortress preserved its significance until the Turkish invasions.
The Citadel had a multifunctional role: it was protecting the valley of the Danube, it was controlling the main commerical route between Buda and Esztergom, and also served as a custom’s house. The fortress consisted of two parts.
The construction of the Lower Castle started under the reign of Béla IV around 1247. It was unique, as the fortress was not located next to the road differing from the common traditions, but the road was crossing the territory of the castle. The most interesting part of the Lower Castle is the so called Solomon Tower. The Tower was named after a false story, stating that Solomon was guarded in this Tower after loosing in the battle for the throne against King Saint Laszlo and Geza.
This unique Hungarian building was constructed based on a southern-German design. Under the reign of Louis the Great King of Hungary, the famous bell-founder Konrád Gaal was operating in the fortress. Today the Tower is hosting a five-storey museum, introducing the history of Visegrád to its visitors.
In 1246 Béla IV started the construction of the Citadel on an area with outstanding geographical characteristics, by the using the money from the family jewels of his wife, Mária Lascaris to build a refugee for the Dominican Order nuns living on the ’Rabbits Island’ (today’s Margaret Island). At that time the plan of the fortress was triangle-shaped, with two towers.
The Old Tower was erected at a location most at risk, and the Gate Tower protected the southern entrance. The significance of the fortress considerably improved during the Anjou era. Once Charles Robert obtained the fortress from Máté Csák, he moved the royal court here in 1323.
The Visegrád Citadel hosted the famous Royal Summit of Kings, and the first Anjou King died in the castle in 1370. The Saint Crown of Hungary was guarded here. When Louis the Great became the King of Poland in 1370, the Polish crown was also stored in the castle. The palace wings and a new external wall was erected during the Anjou reign. Sigismund of Luxemburg extended the fortification with a third set of walls and carried out several lavish constructions.
Following the Turkish reign, after the liberation of Buda in 1686 the Habsburgs conquered the fortress after a 5-day siege. Due to the dissolution of the border castle system the fortification became unwanted and was left to ruin.

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.
