The Tour Magne, or the Great Tower, is the only remnant of the ancient Augustan fortifications. Standing at the highest point of the Nïmes, Mont Cavalier, it overlooks the entire plain and is a focal point for all means of communication.
The tower was originally a dry-stone oval tower, with a maximum height of 18m and already part of a rampart. A structure that was both prestigious and strategic, it represented sanctuary and protected the oppidum. By doubling its height and incorporating it into the town walls, Augustus demonstrated the new power of the colony of Nîmes over the 'City' (in the territorial sense) of the Volcae. When the town’s population abandoned the higher ground, the Tour Magne nevertheless continued to play a military role. It was used to defend against the English during the Hundred Years’ War.
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).
