The Vatican Necropolis, which is under St. Peter's Basilica, can now be viewed via an online pilgrimage thanks to the Vatican website. I was fortunate enough to be able to go on a tour back in the Jubilee year 2000. It was simply amazing! I am glad I can now re-live some of those moments with this great tour.
So, head over to the Vatican website and check out St. Peter's tomb!
