Malta Knights' Reunion In Rome -- The Cardinals who belong to the Order, heading the procession. One of the most remarkable pilgrimages in the history of the Church began on Wednesday, when 600 knights of the Sovereign Order of Malta walked in procession through the basilica of St. Paul-Outside-the-Walls. They represented the most noble families in Europe. This was the first reunion of its kind since the Order left Malta, more than 100 years ago. March 16, 1934. (Photo by Keystone).
