All eyes are on Vatican City Tuesday with just over a day to go until the start of the papal conclave to elect the 267th pope.

The white smoke came out of the chimney on the fifth ballot on March 13, 2013, and Cardinal Jorge Mario Bergoglio was introduced to the world as Pope Francis a short time later from the loggia of St. Peter's Basilica.

Cardinals who will take part in the secret conclave to elect a new Catholic pope began checking into two Vatican hotels on Tuesday, where they will be barred from contact with the outside world as they decide who should succeed Pope Francis.
