Louvre Museum
When in Paris, you cannot not spend a few hours in the Louvre Museum, unless of course you go here for the 10th time and ticked all the must-sees already.... Mona Lisa, Milo's Venus, and lots of other very very old stuff.... If you have the time: book the guided tour, things will come more alive then walking around there just by yourself.
