At the end of a long gallery is the Rotunde du Glacier, a fresh and bright rotunda with a ceiling painted by Clairin (1843-1919) and featuring dancing bacchantes and fauna, along with tapestries illustrating different refreshments as well as fishing and hunting. Completed after the opening of the Palais Garnier, this salon evokes the aesthetic of the Belle poque.
The vault of the Avant-Foyer is covered with mosaics of shimmering colours on a gold background. The view of the Grand Staircase is spectacular. The play of light between mirrors and windows in the Grand Foyer further accentuates the latter's vast dimensions. The ceiling painted by Paul Baudry (1828-1886) features themes from the history of music.
The lyre is the main element: it reigns over all the decorative vocabulary, be it on capitals, heating grids or doorknobs. A copy of Charles Garnier's bust by the sculptor Carpeaux (1827-1875) is located in the centre of the foyer, near a window looking down the Avenue de l'Opera towards the Louvre. The view can be enjoyed even more from the loggia. The Salons du Soleil et de la Lune offer a symbolic and poetic transition to the other areas.
