The first written record of Raikküla manor date back to the year 1469. Later it has been associated with the von Staals, the Kankrins and the von Keyserlings. The luxurious High-Classicist main building was completed on the foundation of a former building in 1820. After a fire in 1960, the house lied in ruins for a long time. Currently, it is privately owned and being renovated. About a kilometre from the manor's centre is a family graveyard of the von Keyserling's family.

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.
