After passing through various hands, in the 1880s the abbey site was bought by
Charlotte de Rothschild, who stabilized the ruins of the church and commissioned the Rothschild family architect
Félix Langlais to restore the 17th-century abbey building with interiors emulating the
chapterhouse, which had remained intact. She used it for a summer home, with stables for her
thoroughbreds on the grounds. In November 1942, the property of Henri de Rothschild and his son was expropriated under the
antisemitic laws of
Vichy France. Vaux-de-Cernay Abbey was sold at auction to the industrialist
Félix Amiot, who moved his private offices there. The estate was also used as an agricultural centre. It was classified as a
historical monument in 1926 and fully protected in January 1994. The abbey mill, which appears in 19th-century landscape paintings, was sold in 2012 and in 2016 opened as a regional museum. 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. ==See also==
