Speaking of Leonardo: I noticed that the Mona Lisa has a new much better (more transparent) protection glass, at least new since I last visited a few years ago. It makes it imho more worthwhile to go see it. Also pro tip, go in February -- there's only a moderate crowd, not a crazy dense throng as in the summer.

Here's another pro-tip: there are other "copies" of the Mona Lisa which, IMHO, are more interesting to look at than the deeply varnished one on display at the Louvre. The Prado Mona Lisa is one I particularly like.
