November 8th 1793; after more than two centuries as a royal palace, the Louvre is opened as a public museum in Paris by the French revolutionary government. Today, the Louvre's collection is one of the richest in the world, with artwork and artefacts representative of 11,000 years of human civilization and culture.
In the 1980s and 1990s, the Grand Louvre, as the museum is officially known, underwent major remodelling. Modern museum amenities were added and thousands of square meters of new exhibition space were opened. The Chinese American architect I.M. Pei built a steel-and-glass pyramid in the centre of the Napoleon courtyard. Traditionalists called it an outrage. In 1993, on the 200th anniversary of the museum, a rebuilt wing formerly occupied by the French ministry of finance was opened to the public. It was the first time that the entire Louvre was devoted to museum purposes.
