But Dina's Great Work was, is, and always will be the Chapel in which he attempted to create an impossible synthesis of universal knowledge including Egyptian tarots, Cabala, signs of the zodiac, etc.
In a vast mosaic with touches of gold, all the gods are called upon and all religions assembled.
Finally, in 1917, with the Western world licking its wounds, Dina signed his work with the terse formula "The Universe is an egg, the egg is a universe."
He died under mysterious circumstances while crossing the Red Sea.
In 1930, Mary Wallace Shillito married pianist Ernest Britt in Paris. In the five years following their marriage, Britt gradually threw away his wife's fortune.
The Avenières property was sold to Mr Guillermin, a high-ranking elected official of the Savoy region, on 20 January 1936.
Six months later, Mr Guillermin auctioned off the castle's furniture and works of art.
Mary Schillito died of an accident on 22 September 1938, one year after her divorce from Ernest Britt.
Mr Guillermin sold the property to a newly constituted real estate company presided over by Count François Maurice Roussy de Sales.
Then, from 1939 to 1941, a new company took over the Château and operated it as a rest home for wealthy families.
In 1942, the property was rented to the 'Secours Suisse aux enfants victimes de la guerre' (Swiss Red Cross organization for child victims of war).
In 1949, the real estate company rented the domain to the Congregation of the Oratory, who turned it into the first-rate Juilly school. The Juilly school bought the property and administered it until 1970.
Mr Duvemay, who bought the property in 1970, sold it to Mr Hausermann in 1981. The latter began restoring the castle but was unable to complete his ambitious and controversial plan to urbanize the site.Now the property of the Domaine des Avenières Real Estate Company, the Château has been operated as a hotel and restaurant since September 1994.
