Pope Leo XIV is scheduled to preside over a solemn Mass at the Basilica of the Sagrada Família in Barcelona to bless the central “Tower of Jesus Christ” on June 10, 2026, marking the 100th anniversary of architect Antoni Gaudí’s death. PR Newswire reports that the event includes the Pope’s blessing of the tower during the Mass, with members of Spain’s national and regional leadership expected to attend, including the King and Queen of Spain, the President of the Spanish Government, and the President of the Generalitat de Catalunya. The Daily Mail describes the occasion as the opening of the tower and notes the long construction timeline, framing it as following 144 years of work. Together, the reports tie the ceremony to both the tower’s completion and the commemorative year for Gaudí, with the Vatican and major public officials in attendance. The sources agree on the date, the location in Barcelona, the central tower’s dedication to Jesus Christ, and Pope Leo XIV’s central role in the Mass and blessing. No other details about the tower’s features or construction milestones are provided in the excerpts.
