Vaux-de-Cernay Abbey

His nephew Peter of Vaux-de-Cernay, also a monk of the abbey, accompanied him on this crusade, and left a chronicle of the Cathars and the war against them.

[1][4][6] During his time as abbot, in 1240, King Louis IX (Saint Louis) visited the abbey on pilgrimage with his queen, Margaret of Provence, who had been unable to have children; the couple's eleven subsequent children were attributed to the water from the spring-fed well serving the abbey, which consequently became a place of pilgrimage.

[6] Towards the end of the fourteenth century the monastery began losing its fervour, both on account of its wealth and because of the disturbed state of the Île-de-France during the Hundred Years' War.

In the seventeenth century the community was restored in spirit by embracing the Reform of the Strict Observance as promoted by Denis Largentier.

[7] Her grandson Baron Henri de Rothschild inherited the property in 1903 and further updated the residence;[7] he it was the site of his experiments in child nutrition.

[9] In November 1942, the property of Henri de Rothschild and his son James [fr] was expropriated under the anti-semitic laws of Vichy France.

[11] In the early 2020s, the abbey was acquired by the hospitality company Paris Society and extensively renovated into a luxury hotel with interiors by Cordélia de Castellane.
