I second that recommendation. It's my favorite part of the Louvre. It's a very castle-looking castle; it feels like it's straight out of a movie.

To my mind, all of the best stuff in the Louvre is in the basement: the Codex Hammurabi, Babylonian artifacts, etc. Yeah, it's all just as stolen as the artifacts in the British Museum that get more attention, but it's more significant than their art collection that are "the greatest" because they said so.

(Not that they aren't also great works. But there are many great works, and the distinction of these has more to do with French nationalism than any serious consideration of artistic merit.)
