The mini-site is is dedicated to the Papal Basilicas and Chapels. Various bits of information are provided, as are virtual tours of these places -- including the like of the Pauline chapel.
However, what I was particularly struck by myself -- and hence my reference to the current feasts -- is the tour of the ancient Vatican Necropolis.
This particular tour shows aspects which are not as readily seen by the broader public touring St. Peter's -- aspects of significant interest, both Christian and Roman. I think many of our readers will appreciate these pages and what they have to offer.
