3D conclave: what it looks like to elect a new pope

For centuries, the leader of the Catholic Church has been elected in a highly secretive gathering known as “conclave,” meaning “with key” in Latin – a nod to how cardinals used to be locked in until a new pope was selected. CNN’s Boris Sanchez walks through a 3D visualization showing what the process may look like.

Correction: A previous version of this video inaccurately stated the next pope’s successor number. The next pope will be the 267th pope.
