Pietro Zander of the office in charge of construction matters related to St. Peter’s Basilica shows Pope Francis something on a tablet computer as the pope visits the necropolis below the main basilica at the Vatican April 1. Looking on, at right, is Bishop Vittorio Lanzani, delegate of the Fabbrica di San Pietro. The necropolis is where St. Peter’s tomb has been venerated since early Christian times and where the first church dedicated to him was built. The tomb is two levels below the main altar of the modern basilica. (CNS photo/L’Osservatore Romano via Reuters) (April 1, 2013) See FRANCIS-PETER (UPDATED) April 1, 2013.
