You might not think of a botanic garden as a historic site, but the Royal Botanic Gardens at Kew, London (a UNESCO World Heritage Site) have a firm place in the history of gardening. Established from a collection of royal estates in 1759, they demonstrate different garden styles through the centuries. The gardens are also home to 44 historic buildings, including royal residences, Victorian greenhouses and garden follies.
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.
