The Jardin Exotique de Monaco is a botanical garden located on a cliffside in Monaco. The succulent plants were brought back from Mexico in the late 1860s. By 1895, Augustin Gastaud, who served as the Chief Gardener of the State Gardens of Monaco, grew the succulents in the Jardin St Martin.
Albert I, Prince of Monaco acquired a piece of land in Les Moneghetti in 1912. He commissioned Louis Notari, the Chief Engineer of Monaco, to build a new garden with footbridges. During the construction, Notari found a grotto underneath in 1916.
The grotto was opened to the public in 1950, but it may only be visited with specialized guides. Evidence of prehistoric human inhabitants has been found in the cave. There is a museum of Prehistoric Anthropology within the Exotic Garden displaying many of those prehistoric remains. It was founded by Prince Albert I in 1902.
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.
