Built for the Universal Exhibition in 1900, the Grand Palais spans an area of 775,000 square feet in the form of an 'H'. Listed as a historic monument, it is recognisable from a distance thanks to its glass roof, the biggest in Europe. The building is managed by EPGPCE, a public body also responsible for programming the events in its main interior space, the Nave. Other facilities housed in the building include the Galeries nationales, managed by the French museum board (Réunion des musées nationaux), and the Palais de la Découverte, an interactive science museum.
