The Musée du Louvre in Paris is one of the world's most renowned and visited museums, originally established as a royal palace in the 12th century and transformed into a public museum during the French Revolution in 1793. The museum features a vast collection of over 400,000 works, including masterpieces from different civilizations, with notable pieces such as the Mona Lisa and the Winged Victory of Samothrace. Major renovations and expansions, including the iconic glass pyramid entrance designed by I.M. Pei, have modernized the museum while preserving its historical significance.
