How a controversial glass pyramid modernized the world’s most famous royal palace museum

In short: When I.M. Pei designed the Louvre Pyramid, it was a polarizing addition to a historic French landmark. Completed in 1989, this steel-and-glass structure transformed the museum’s accessibility by serving as the gateway to a vast underground complex, forever changing how millions of visitors experience the historic palace.

The Louvre Pyramid was a cornerstone of President François Mitterrand’s ambitious grands projets, designed to rationalize and modernize the museum. Before this intervention, the Louvre was a sprawling, disconnected complex of buildings that had evolved over centuries, originating from a 12th-century fortress built by Philip Augustus. By the 1980s, the museum required significant remodeling to accommodate its status as the world’s most-visited art institution.

Architect I.M. Pei’s solution was to construct a massive underground network beneath the Cour Napoléon and the Cour du Carrousel. This subterranean space was designed to house essential amenities, including shops, exhibition areas, an auditorium, a tourist bus depot, and a cafeteria. The pyramid serves as the primary ground-level entrance to this hub, allowing natural light to flood the visitor hall below while maintaining clear sight lines of the surrounding historic architecture.

The project was not without controversy, as the starkly modernist steel-and-glass structure contrasted sharply with the traditional palace facade. However, the renovation was essential for the museum’s evolution. Following the completion of the pyramid in 1989, the museum continued its expansion, notably with the 1993 opening of the rebuilt Richelieu wing—also designed by Pei—which added over 230,000 square feet of exhibition space. This allowed the entire Louvre to be dedicated to museum purposes for the first time, cementing its role as a global cultural anchor.
