Guise castle is a medieval fortification in the town of Guise, in northern France. Originally an early medieval wooden motte and bailey castle, it was rebuilt in stone and then massively expanded during the 12th-16th centuries. It was remodelled by Marquis de Vauban in the late 17th century to meet the advances in sIege technology then taking place. Much of the castle was reduced to rubble during the First World War and, from 1952 onwards, it has been undergoing restoration by the Club du Vieux Manoir. Nowadays it is a popular tourist site.
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).
