The Vatican Gardens have been a place of quiet and meditation for the popes since 1279 when Nicholas III moved his residence back to the Vatican from the Lateran Palace. Within the new walls, which he had built to protect his residence, he planted an orchard (pomerium), a lawn (pratellum) and a garden (viridarium).
Created around the hill of Saint Egidio (where the Palazzetto del Belvedere is located today) and the courtyards of the Vatican Museums, this was to be the first garden in the Vatican. However, should you visit the Vatican Gardens today you would begin by viewing a totally different area from that first orchard, one located in a more recent addition to what is now Vatican City State. It is there that larger and more recent gardens have been planted, covering together with the original garden about half of the 44 hectares of Vatican City.
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.
