I've been lucky enough to visit both the Sistine Chapel and the Louvre to see the Mona Lisa. I've been to the Sistine Chapel twice (2003 and 2011) and both times it was very crowded and remarkably quiet. Even while waiting on line to get in it was very quiet. I was surprised. The crowd in front of the Mona Lisa was a bit louder but still very quiet. Many people were taking photos but there were signs up, and people around to remind you, that flash photography was prohibited. Neither experience was as tranquil as I would have liked to take in such awesome works of art but it didn't bother me much because it honestly felt like everyone there was doing their best to not disturb everyone else's experience. I guess that's just the nature of visiting two of the most famous works of art on the planet.
