The Jardin Exotique de Monaco is a botanical garden located on a cliffside in Monaco. It was opened in 1933, and has a rich collection of over a thousand species of succulent plants, especially cactuses.
At the foot of the cliff, ranging in altitude between 321 and 131 ft, there is a large natural underground cave with caverns displaying many stalagmites and stalactites, draperies and columns. It was opened to the public in 1950, but can 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.
