From the Vatican:

Maintenance and enhancement work on the lighting systems of St. Peter’s Basilica is currently underway.

The Fabric of St. Peter is renovating the lighting of Michelangelo’s dome with the objective of better illuminating the drum of the large dome, which is undergoing functionality tests and light intensity checks.

The technical operations, which also take place during nighttime hours, seek to highlight the grandeur of the Renaissance architecture.

The new, state-of-the-art lighting fixtures will provide a more intense, calibrated, and well-distributed light, which will further enhance the dome and create a striking atmosphere.

This project is part of a series of periodic maintenance interventions carried out by the Fabric of St. Peter to preserve and enhance the Basilica and its artistic structures.

The work will continue over the coming weeks.
