According to Wikipedia:
"St. Peter's Basilica has the largest interior of any Christian church in the world, holding 60,000 people.[1] It is regarded as one of the holiest Christian sites. It has been described as "holding a unique position in the Christian world"[2] and as "the greatest of all churches of Christendom".
Religion aside, I was impressed. This I gotta see!
Waiting for the Pope! He is going to talk to this massive crowd in front of the Basilica.
