Mona Lisa
Now, The Louvre is amazing. However, seeing the Mona Lisa is disappointing. You go to a relatively narrow hallway, and there is a pane of glass 15 feet in front of the painting. I understand it needs to be protected and preserved, but you can’t see very well through that.
I always find it funny seeing people hurry past exceptional works down that long hall to stand in a crowd and stare at a small dark painting.
