Share As of May 18, Italians were allowed to attend Mass once again, and St. Peter's Basilica was no exception. After taking necessary precautions, pilgrims were able to enter the basilica once again. On May 21, St. Peter's Square also reopened. At the end of the month, on May 31, the pope prayed the Regina Coeli from the window of the Apostolic Palace. The last time he did this was on March 8. POPE FRANCIS “Today the square is open. We can see each other again! What a joy!” Hours earlier, he celebrated the Pentecost Mass. There, he warned that the Holy Spirit is not present in the souls of narcissists.
