The #LouvrePyramid is a large glass and metal pyramid, surrounded by three smaller pyramids, in the main courtyard of the Louvre Palace in Paris. The large pyramid serves as the main entrance to the Louvre Museum. Completed in 1989, it has become a landmark of the city of Paris. The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal and Rice Francis Ritchie of Paris. The pyramid and the underground lobby beneath it were created because of a series of problems with the Louvre's original main entrance, which could no longer handle the enormous number of visitors on an everyday basis. Visitors entering through the pyramid descend into the spacious lobby then re-ascend into the main Louvre buildings. (Image copyrights belong to their respective owners)
