The Louvre in Paris is one of the world’s largest and most visited art museums in the world. The museum opened in 1793 and is housed in the Louvre Palace, a former royal palace. The famous glass pyramid which in the main courtyard of the Louvre Palace was added in 1989 and serves as the main entrance to the museum. Its exhibits come from such diverse origins as ancient Egypt, classical Greece and Rome, medieval Europe and Napoleonic France. Its most famous exhibit, of course, is Leonardo da Vinci’s painting of the Mona Lisa, generally to be found surrounded by hordes of camera-flashing tourists.
