The Citadel of Montpellier was built between 1624 and 1627, after several rebellions under the orders of Louis XIII in order to keep watch over the town. In the 20th century it became the Joffre Barracks, named after Joseph Joffre, and since 1947 the citadel has been an academic campus - the nationwide famous Lycée Joffre.
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.
Today the two southern bastions and the wall linking them have been preserved. There is a palm grove planted at the base of the wall. On the west side there remains the Bastion du Roi, which has been broken in multiple places to allow for construction of automobile access roads and pedestrian footpaths between the northern parking lot and the center of Montpellier. The walls and their embrasures are still visible.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
