From September 29 to October 23, 2026, restoration work will be carried out on the South facade of the Palais idéal and the top of its East facade.
This work is essential to preserve the monument, ensure its longevity, and allow future generations to continue discovering it. Maintaining and restoring the Palais idéal means caring for an exceptional work, built to stand the test of time, while continuing to share it with all audiences.
Throughout the duration of the construction site, the Palais idéal and its museum space remain open for visits.
