On November 18, 2026, Pope Leo XIV will celebrate Mass in St. Peter's Basilica in Rome to commemorate the anniversary of its official consecration 400 years ago. To mark this important anniversary, the Holy See has announced the launch of new spaces and services — particularly digital ones — for pilgrims and tourists alike. They include an app that provides instant translation of Masses and a font inspired by Michelangelo's handwriting.
In 1626, Pope Urban VIII officially consecrated St. Peter's Basilica in Rome. The building was constructed on the site of the former Constantinian basilica, whose destruction had been decided by Pope Julius II in 1505. Designed by the greatest minds of the time — Raphael, Bramante, Michelangelo, Bernini — this edifice, which houses the tomb of the apostle Saint Peter, is now one of the most visited places in the world, with nearly 12 million pilgrims and tourists each year.
The 400th anniversary of the consecration of the world's largest Catholic church will be an “opportunity to remember,” but also to “update,” announced Cardinal Mauro Gambetti, archpriest of the basilica, at a press conference held at the Vatican on February 16, 2026. He explained that, unlike his predecessors who had been forced to destroy the previous building, “Pope Leo can afford to renovate without destroying,” and that he intended to continue to make this place “an open door for all those who seek God.”
Using the latest technology
Thanks to the sponsorship of the oil company Eni, a complete three-dimensional map of the structures of the basilica was produced. It includes previously unknown data on its foundations, thanks to technologies that can probe more than 300 feet below the ground. The operation lasted two months and cost the Italian group “several hundred thousand euros,” announced its representative Claudio Granata.
Alberto Capitanucci, project manager for the Fabbrica di San Pietro (the Vatican body in charge of the basilica), also highlighted the installation of a dozen sensor units in the basilica to collect data on its “state of health.”
Cardinal Gambetti also announced the opening of new spaces in the basilica complex to better manage the influx of tourists. In particular, he plans to open the entire terrace on the roof to the public, where the existing refreshment area will be doubled in size.
An educational section on the construction of the basilica and an interactive section where visitors can share their photos and messages on a “wall” are planned for spaces on the roof of St. Peter's. A new “Via Crucis” created by Swiss artist Manuel Andreas Dürr will also be inaugurated in the basilica on February 20.
Finally, several innovative projects have been presented in the digital realm. One example is a new application powered by artificial intelligence that will translate the ceremonies taking place in the basilica into 60 different languages. Another digital project is a new institutional font called “Michelangelus,” based on Michelangelo's handwriting, which will be included in Microsoft's Office suite (a company with which the basilica has already collaborated recently). Finally, the “Smart Pass” service, a new real-time reservation system for accessing the basilica, will be available to better control the flow of visitors.
