My favourite area within the walls of the Louvre is the sculpture galleries. Most everyone flocks to the Mona Lisa, for me it's straight to these petrified souls.
I understand paint, I've used it, not as well as I wish I could.
But stone is a different animal. To make it look like fabric draped over a shoulder, like flesh being pierced by claws...it's absolutely amazing! And if I ever find myself in the Louvre again, I'm sure I'll head straight for the sculptures again.
