Do you remember when you first walked through the Vatican Museums, either on your own or with a guide? I have visited twice, and both times are somewhat of a blur. I remember thinking, "I wish all these other people weren't here. I want to stay longer."
Today, thanks to technology, you can take your time on this virtual visit!
Use the + or - buttons in the bottom left hand corner to zoom or go back. Use the M button to move around. Don't forget the ceiling!
