Of all the museums in the world, the Louvre in Paris is the largest by gallery space, covering more than 650,000 square feet in total. The museum was once a medieval fortress, and the home for French kings before becoming the vast Parisian Museum in 1793 that we know and love today.
The Louvre is home to some of the most important art and artifacts in the history of human civilization, including Leonardo da Vinci’s Mona Lisa (1519), The Winged Victory of Samothrace, Théodore Géricault’s Raft of the Medusa (1818-19), and Eugene Delacroix’s iconic masterpiece Liberty Leading the People, (1830), to name just a few. Because of its incredible scale, one could spend literally days wandering through the Louvre, which is why so many people come back again and again to take in more.
