The Inverted Pyramid
In 1993 the underground area expanded with the opening of a modern shopping mall, the Carrousel du Louvre. It is anchored by an inverted glass pyramid, known as the Pyramide Inversée (Inverted Pyramid), which nicely complements the Louvre Pyramid.
The pyramid was designed by the American architecture firm of Pei Cobb Freed & Partners, who created a smaller version of Pei's pyramid, turned it upside down right and suspended it right above a small stone pyramid.
