For eight centuries the Louvre has stood as a unique national monument, central to the people and spirit of France. In 1983, President François Mitterrand requested that it be modernized, expanded and better integrated with the city — all without compromising the integrity of the historic building. The challenge was magnified by the fact that the Louvre was originally constructed, and used for most of its life, as a royal palace; it was fundamentally ill-suited to serve as a museum. The two-phase solution involved the reorganization of the long linear building into a compact U-shaped museum around a focal courtyard. A centrally located glass pyramid forms the new main entrance and provides direct access to galleries in each of the museum's three wings. Critically, the pyramid also serves as a skylight for a very large expansion building constructed under the courtyard to provide all the public amenities and technical support required in a modern museum. Corollary objectives for improved urban integration led to the transformation of surface parking into a three-hectare fountain plaza. Closed passages through the building were opened as public rights of way, underground services and parking relieved congestion, and a 55,000m2 mixed-use complex, supplementary but independent of the museum, was designed to help finance the project and reinvigorate the heart of Paris. The half-mile-long Louvre, previously an obstacle to circulation, thus became a vital gathering place and bridge to the surrounding city.
