Around 135 cardinals will enter the Sistine Chapel on Wednesday to begin the process of electing the new leader of the Catholic Church, and the Vatican is going into overdrive to ensure that what happens in the Sistine Chapel stays in the Sistine Chapel.

The Sistine Chapel in the Vatican has been prepared to host 133 cardinal electors for the upcoming conclave to choose the 267th Pope.

The papal smoke signals are ready. Vatican workers on Friday hoisted a chimney onto the roof of the Sistine Chapel, which will be used in burning the ballots for the conclave that will elect a successor to Pope Francis.
