Fiat Lux Fiat Lux A public art projection to light St. Peter's Basilica and inspire change around the climate crisis

Watch Fiat Lux


Using the language of “visual poetry,” we are lighting up St. Peter's Basilica to reinforce the idea of a responsible stewardship for our common home a notion touched on by both the current Pope Francis and the earlier one. The project signals the start of the Jubilee but also the United Nations Framework Convention on Climate Change, known as COP21, which continues in Paris through Dec. 11.

In keeping with the saint who inspired his papal name, Francis has made environmental justice a cornerstone of his vision. His encyclical, issued in June, forcefully calls for action to stem environmental destruction and climate change, which has the most adverse impact on the world’s poor.
