He also announced that on Friday, March 27, at 5p.m.(UK time) he would preside over a prayer service in front of an “empty” St. Peter’s Square, which will include scripture readings and adoration of the Blessed Sacrament. At the end of the event, he will offer a special Urbi et Orbi blessing, offering all who participate a plenary indulgence. Traditionally only given at Christmas and Easter, the Urbi et Orbi is a blessing that goes out to the people of Rome and to the world. The decision to offer the blessing outside these two major Catholic feast days is, if not unprecedented, extremely rare. Urbi et Orbi will be broadcast live from the Vatican: https://www.vaticannews.va/en/pope.html
