The Chartreuse Notre-Dame des Prés was a Carthusian monastery (Charterhouse) in northern France, at Neuville-sous-Montreuil. The charter of foundation is dated from the chateau d'Hardelot on 15 July 1324; the church was consecrated in 1338.
The foundation, being close to Calais, was liable to disturbance in time of war. Thus it was often sacked by the English during the wars of the fourteenth and fifteenth centuries, and was for a time abandoned. The religious returned when peace was restored.
In 1542 the monastery was again wrecked by the Imperial troops and in the wars of religion fresh troubles attended the community. Finally the house was rebuilt by Dom Bernard Bruyant in the latter part of the seventeenth century and remained undisturbed until the French Revolution. In 1790 the monastery was suppressed and its property sold by auction the following year.
Eighty-two years later the Carthusians repurchased a portion of their old estate and the first stone of the new monastery was laid on 2 April 1872. The work was pushed forward by the Prior, Dom Eusèbe Bergier, and was finished in three years. The monastery contained twenty-four cells in its cloister.
La Chartreuse de Neuville has dozens of cloisters, chapels, a library and other rooms. It was once the home of the printing press for all the Charterhouses of Europe 1800s. But the equipment was transferred to St Hugh’s Charterhouse (there are plans to have it returned).
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
