It was such a spiritual completion for me when I walked through the archway into the Vatican and then to walk through the doors into the Basilica. It is awe inspiring. Even without the spiritual aspect, it is a gorgeously constructed building with so many beautiful pieces by all of the greats of the Renessaince. Having been to many churches while in Italy, I can easily say that if you go to no other, you must go to the Vatican. The Vatican Museums are also well worth the time.
