Many attribute the origins of the Louvre to King Francis I (1515-1547), although paintings were already collected under previous French kings and can still be found in the exhibition today. In any case, Francis I was in close contact with Leonardo da Vinci, as a result of which some of his works entered the French collection shortly after his death. Until the French Revolution, however, the Louvre was not open to the public. In August 1793, exactly one year after the abolition of the monarchy, the Louvre was reopened as the Central Art Museum of the Republic. As its design suggests, the museum's iconic glass pyramid is comparatively modern, built in the late 1980s as part of a redesign process that lasted until 1999.
