Voting will take place in the Sistine Chapel, with ballots continuing in succession until any candidate secures two-thirds of the available votes. If no clear choice has emerged after three days, balloting is suspended for 24 hours to allow cardinal electors time to reflect.

Wearing bright red vestments, the cardinals processed down the central aisle of the basilica as the Sistine Chapel’s boys’ choir sang. They took up their seats around the main altar, which lies above the traditional burial place of St. Peter, considered to be the first pope.
