Musée du Louvre Memory - the Winged Venus of Samothrace will be the first marvelous sculpture to welcome you upon entering the Louvre museum galleries. It stands at the cross landing of the staircase leading to the exhibits. The stairs to the right of the statue is the gallery where Mona Lisa is seen.
Musee Rodin: This is a very underrated museum in Paris. The sculptures are housed both in a lovely 18th century private palace where Rodin lived for awhile, and also outside in a simply breathtaking garden. Among his many famous sculptures here is "The Thinker".
