The Royal Opera of Versailles is the main theatre and opera house of the Palace of Versailles. Designed by Ange-Jacques Gabriel, it is also known as the Théâtre Gabriel. The interior decoration by Augustin Pajou is constructed almost entirely of wood, painted to resemble marble in a technique known as faux marble. The excellent acoustics of the opera house are at least partly due to its wooden interior. The house is located at the northern extremity of the north wing of the palace.
