Undoubtedly the most famous room in the chateau, the Hall of Mirrors in part of an enfilade that includes the flanking War Salon and Peace Salon. Following French victory in the Franco-Dutch War, the three rooms were constructed and designed to display the chronicle of the war, impress all who entered, and--of course--reflect the power of glory of France and her king. The ceiling paintings by Charles Le Brun do all three.

The seventeen windows each stand opposite twenty-one mirrors, a combined total of 357 mirrors. They reflected France's wealth at a time when mirrors were difficult to produce and afford.

In the twentieth century, several dignitaries gathered here in this room to sign the Treaty of Versailles, thus ending the First World War.
