A palace that became a museum
The Louvre began as a medieval fortress, became a royal palace, and opened as a public museum in 1793. Its collections span antiquities, Islamic art, European painting, and sculpture across three named wings around the Cour Napoleon.
The museum sits on the historic axis that runs from the Cour Carree through the Tuileries to the Arc de Triomphe. It is one of Paris's most visited indoor attractions, so timed tickets and a short list of rooms make a better visit than trying to cover the whole map.
