The Royal Galleries of Saint-Hubert, or Galeries Royales Saint-Hubert, built in 1847, were designed by the architect Jean-Pierre Cluysenaar (1811-1880) in the Neoclassical style.
The Galeries consist of two large galeries, the Gallery of the King and the Gallery of the Queen, which are 8 meters wide and 213 meters long, and a smaller galley on the side, the Gallery of the Princes. The galleries are covered with a glass structure on the top.
