The Duchesse de Mouchy turned La Mission Haut-Brion in a nice gathering place for family and visitors.

The Dillon family first came to know and appreciate La Mission in the summer of 1985. It was the fiftieth year of their ownership of Haut-Brion. An Anniversary Party took place in the park at Haut-Brion. Four generations of the Dillon family came for the celebration.

The Duchesse de Mouchy redecorated a small pavilion for the use of journalists (accustomed to staying at La Mission during the time of the Woltners) and other friends. Luxembourg memorabilia and curios have found their place therein.

All lunches and dinners concerning La Mission are held in its château. The Duchesse de Mouchy decorated it with material from the anniversary party and furniture from Haut-Brion and Luxembourg. Furniture was bought at various sales and antique dealers in Bordeaux. Continuing the search for suitable acquisitions is an ongoing and pleasurable task.
