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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
