The Jardin des plantes de Montpellier (4.5 hectares) is a historic botanical garden and arboretum maintained by the Montpellier University.
The garden was established in 1593 by letters patent from King Henri IV, under the leadership of Pierre Richer de Belleval, professor of botany and anatomy. It is France's oldest botanical garden, inspired by the Orto botanico di Padova (1545) and in turn serving as model for the Jardin des Plantes de Paris (1626).
The Montagne de Richer lies within the garden's oldest section, which also now contains a systematic garden. The garden was expanded twice in the 19th century. Its orangery was designed by Claude-Mathieu Delagardette (1762–1805) and completed in 1804, the arboretum was landscaped in 1810, and the English Garden, with pool and greenhouse, dates from 1859. The monumental Martins greenhouse opened in 1860.
Today the garden contains about 2,680 plant species, including 500 native to the Mediterranean region. Of these roughly 2,000 species are grown outdoors, and 1,000 under glass.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
