Spent my 5th day in Paris at the Louvre. The ceilings in part of the Louvre are almost more remarkable than the art exhibits in them. I think honestly that you can see the Mona Lisa better from a replica than the actual painting with the reflective glass and 10 foot guard rail. And holy shit, Napoleon had the most ridiculous "apartment" I have ever seen. If you go to the Louvre and are into architecture I highly suggest checking it out. It's tucked away in a corner but it's definitely worth it to find. I can't wait to go back and explore more!
