This extensive site covers the art, history and architecture of the Vatican Basilica. It includes numerous pictures, an interactive floor plan map and the entire text of several books and scholarly articles. If you have ever wondered which saint was on top of the Colonnade or are doing historical research, St. Peter's Basilica.org is the place to visit for this and much more.

St. Peter's is not only home to the Pope, but is our spiritual home, where the Church has nurtured and raised Christians through her two thousand year history. However, for many of us St. Peter's is too far away to visit. This website is a wonderful way to experience her beauty and richness from your own home.
