To see the Sistine Chapel, you have to take a tour through the museum first. It’s worth it because of the huge collection of Roman Artifacts through both Ancient Rome and the Rennassaince. The tour takes about an hour before you go to the Sistine Chapel. They don’t allow pictures once you get into the Sistine Chapel, and they move you through it pretty quickly. We could only stay for about 10 minutes. Still worth it!
