The origin of the name Torbemfeldt is unclear but it may refer to Torben Nielsen (died 1310) who was married to a sister of Marsk Stig's first wife. Torbensfeldt is first mentioned in 1377. Early owners include members of the noble Moltke, Gøye and Brahe families. In 1668 the estate was acquired by King Frederick III who renamed it Frydendal. The king died in 1670 and his son Prince George ceded the estate to Christoffer Parsberg in exchange for Jungshoved at Vordingborg in 1671. An important figure in the central administration, Parsberg was created count that same year. However, he died just a few months later and the property was then owned by different noble families before being acquired by Christian Rosenkilde Treschow in 1873. Torbenfeldt has been owned by members of the Treschow family since then. The name of the estate was changed back to Torbenfeldt in 1906.
The three-winged main building is located on an artificial island in a small lake and reflects the long history of the property. Part of the south wing dates from the 15th century but was altered and expanded with a tower in the 1650s. The eastern gate wing is from 1577 but was adapted in 1755. The north wing is from 1767 except for the corner tower which is from 1906 when the entire complex was restored by C. M. Smidt. Frydendal Church is located closeby.
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.
