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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
