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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
