The Louvre is the world's most visited museum and one of its greatest — a former royal palace whose 35,000 works span 9,000 years of human civilisation. The building itself is extraordinary: a harmonious mix of Renaissance and 19th-century wings wrapped around I.M. Pei's glass pyramid, which opened controversially in 1989 and is now beloved.
Go in with a plan or the scale will defeat you. The Venus de Milo, Winged Victory of Samothrace, and Mona Lisa are the non-negotiables, but they draw enormous crowds. The Vermeer and Dutch Golden Age rooms on the second floor of the Richelieu wing are often uncrowded and breathtaking. The Mesopotamian antiquities — including the Code of Hammurabi — are endlessly fascinating and almost deserted.
Book tickets online and arrive at opening to beat the worst of the queues. A visit of three to four hours covers the highlights without museum fatigue setting in. If you have a Paris Museum Pass, use the Richelieu entrance to skip the main pyramid queue.
