The Savoy Castle is an 18th-century Baroque style palace. Construction of the spacious home was begun in 1702 at the commissioning of Prince Eugene of Savoy and finished in approximately 1722. Prince Eugene of Savoy acquired Csepel Island in 1698, and thereafter began the planning process of this 'maison de plaisance'.
Eugene commissioned Johann Lucas von Hildebrandt, a student of the Roman Carlo Fontana, to design the castle. Seven letters from Hildebrandt to the prince remain in the archives of the Gonzaga family in Mantua and evidence planning and construction information about the castle.
The castle has side-wings which were completed in 1714, and the whole construction process was finished around 1720 to 1722. The prince did not reside in Ráckeve mansion after it was finished, and following his death, the estate was appropriated by the Crown.
Under the reign of Maria Theresia of Austria, the mansion and the adjoining land in Csepel was managed by the Hungarian Chancery. In 1814, the middle part of the mansion, along with the stately Baroque cupola, was destroyed by fire; what is seen today was rebuilt after the fire.
Until its reconstruction in the 1980s, the mansion suffered constant decline. The castle has enjoyed renovation and revitalization, and it is now used as a hotel, which is called the Savoyai Mansion Hotel.

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.
