As promised, some further photos, beginning with the following photos which come courtesy of Rinascimento Sacro which show the final day of the pilgrimage and the Solemn Pontifical Mass offered by Cardinal Canizares Llovera at the altar of the Chair in St. Peter's Basilica, Rome.
Here are a few more, by way of this Facebook page.
And finally a couple more as found on Le Forum Catholique.
