If fanciful pictures of saints, Virgin Mary's, and naked cherubs is your thing, then you should love the Italian and Spanis department of the Louvre. This collection is primarily contained in the most famous area of the Louvre, the Grande Galerie. There are paintings by Raphael, Leonardo da Vinci, and Titian. Here is where you'll see the Mona Lisa. This is also where you'll find the biggest crowds.
