Vatican installs new chimney to signal pick of next pope

Workers attached a chimney atop the Sistine Chapel on Friday, ahead of the election process for the next pope.

The chimney, which is attached to the chapel before a new pope is elected, will signal to the public the election of Pope Francis’ successor.

With the death of Pope Francis last month, cardinals, senior members of the Catholic Church, will gather on Wednesday, May 7, for what’s known as a “conclave” to determine the next pope and head of the some 1.4 billion Catholics around the world. There are currently 135 cardinal electors, and to join the conclave, cardinals must be under 80 years old.

That’s when “the verbal and communicative gates go down,” Jensen said. “There is no further communication until a pope has been elected, aside from smoke.”

As the cardinals deliberate, they vote until they reach a two-thirds majority agreement on who to elect. With each vote, they burn their ballots in a stove installed in the Sistine Chapel for this purpose. If black smoke plumes from the chimney, the cardinals aren’t in agreement and will need to vote again. Once white smoke can be seen from the chimney, it signals to the public that the Roman Catholic Church has a new leader. The process relies on chemicals to produce the desired color.

Regarding how long conclaves usually last, Jensen said that all of the conclaves from the 1900s onward have ended in under four days. Francis was elected pope at the end of the conclave’s second day in 2013.
