Military history In 1621, King Louis XIII arrived with soldiers to quell a
Huguenot rebellion; he took over the city after an eight-month siege. The king ordered that a royal citadel close to the city be constructed to control the city and the surrounding region, where there was a large Huguenot population. The citadel was built between 1624 and 1627 between the fortifications of the
Écusson, or old town, and the coastal plain of the River Lez. It was separated from the city proper by a wide
esplanade, looking over the floodplain of the Lez. It comprised four
bastions organized in a square: facing the city was the
Bastion du Roi ("King's Bastion") to the northwest and the
Bastion de la Reine ("Queen's Bastion") to the southwest; facing the floodplain was the
Bastion de Montmorency to the northeast and the
Bastion de Ventadour to the southeast. The buildings within the citadel have been reconstructed multiple times. The last reconstruction before the citadel was converted into an educational building was in 1863. Under the
Ancien Régime, the citadel held royal troops as well as detachments of conscripted forces from
Bas-Languedoc. Later, it became a barracks of the 2nd regiment of Génie.
Scholarly history During the 19th century, it became clear that the
high school for young men in Montpellier was too small: having been built near the esplanade in 1804 in the same place as a former
Jesuit school, by the later part of the century, the high school and its students were dispersed throughout two other sites north of the old town. In 1947 city authorities decided to move the high school into the citadel, which had since become the Joffre Barracks. The first classes were held there on 1 October 1948, and the last students were moved in during October 1959. Since then, the buildings have been adapted to present-day life and new buildings for classrooms have been added. The powder magazine of the
Bastion de Montmorency has been converted into an olympic pool and large gymnasium, and the nearby fields into athletic fields. The academic campus, constituted of the
middle school, high school and
classes préparatoires, occupies 15 hectares. ==Remains still intact==
