Firefighters install a temporary chimney on the roof of the Sistine Chapel on May 02, 2025 in Vatican City, Vatican. The chimney used to communicate the choosing of a new Pope is erected on the roof of the Sistine Chapel today, ahead of Conclave beginning on the 7th May. Cardinals vote for their chosen candidate, and if there is no majority, the ballots are burnt with additives giving off black smoke. Once there is a majority, the votes are burnt without additives, giving off the white smoke signal that a new Pope is chosen. Mario
