A large historical site, exhibition hall and museum complex located at the Champs-Élysées, its construction began in 1897 as part of the preparation works for the Universal Exposition of 1900.
The structure was built in the style of Beaux-Arts architecture. The building reflects the movement's taste for ornate decoration through its stone facades, the formality of its floor planning and the use of techniques that were innovative at the time, such as its glass vault, its structure made of iron and light steel framing, and its use of reinforced concrete.
When one of the glass ceiling panels fell in 1993, the main space had to be closed for restoration work, and was not fully reopened to the public until 2007.
A little known fact is that the Grand Palais has a major police station in the basement which helps protect the exhibits on show.
The Grand Palais is only open when an exhibition is organized.
