In 1968, the property was opened for public tours. A major restoration was completed starting in 1976 and it was continuing in 2017; the roof repair alone took six years. The Baroque ceiling in the Chambre des Muses, "decorated by Charles Le Brun's workshop", was restored in 2016–2017 and was first shown to the public in March 2017. The business is now administered by their three sons: Alexandre, Jean-Charles and Ascanio de Vogüé. "We don’t care about the aristocratic part of this life," said Alexandre de Vogüé, but they are determined to continue the preservation. "We have a ten-year plan, detailing what to do and when; a plan that includes a project of infrastructure restoration, restoration of the garden, and smaller projects; all with anticipated costs next to it. We make this list public for our donors, and people can sponsor a special project, such as restoring a statue in the garden," Alexandre told a reporter in 2017.
