Its interior is described as "Louis XIV style". There are several hundred chambers there, the most famous of which is the so-called Solar Room, also known as the Hall of Mirrors.
It is the largest room in the entire palace (next to the palace chapel, the Court Opera, and the Galerie des Batailles), filled with 17 huge mirrors that illuminate the room. There are frescoes on the vault showing the military successes of Louis XIV.
The Hall of Mirrors was the site of events of great historical importance, including the proclamation of the German Empire and the signing of the Treaty of Versailles.
