Whether you are Catholic or not , you can tour the Vatican on your computer. You can spend as much or as little time as you want on it, keep it permanently if you wish, and explore it at leisure. Don’t forget to turn up the volume and remember the close-up tool is your friend (lower left corner). Also use your curser to click and drag, and you can move to the ceiling or 360 degrees or take any perspective you wish to take. You can zero in on the smallest feature of a painting. Whether you have seen the Vatican or not, you have never seen it this well.
