The oldest part of the Rákóczi castle, the five-storey Red Tower, dates from the late 15th century – inside you’ll find period rooms in excellent condition. Note that this can only be visited by guided tour.
The Renaissance-style Palace Wing, connected to the Red Tower by a 17th-century loggia called the Lorántffy Gallery , was built in the 16th century and later enlarged by its most famous owners, the Rákóczi family of Transylvania. Today, along with some 19th-century additions, it contains the Rákóczi Exhibition, devoted to the 1703–11 uprising and the castle’s later occupants. Bedrooms and dining halls overflow with furniture, tapestries, porcelain and glass. Of special interest is the small five-windowed bay room on the 1st floor near the Knights’ Hall , with its stucco rose in the middle of a vaulted ceiling.
References:The Clementinum is a historic complex of buildings in Prague. 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.
