In an April 29 statement, the Vatican said “the oath of the officials and attendants of the conclave will take place” May 5 in the Pauline Chapel, not far from the Sistine Chapel where the cardinals will vote for the next pope.

The oldest and youngest cardinals—and some famous papal ‘lasts.’

The conclave to elect the next pope will open on May 7, Vatican officials announced today. The cardinals meeting in plenary assembly (called general congregations) in the Vatican decided the date this morning, April 28.
