World Youth begins in Poland this Wednesday, marking one of the largest religious gatherings anywhere in the world.

Initiated in 1985 by Saint Pope John Paul II, it is held interationally every two or three years and at a diocesan level every year. The event is normally finished with a Mass and in 1995, five million people at the closing Mass in the Philippians broke the record for the largest single religious event.

The final mass in Krakow, Poland next Sunday promises to be equally spectacular but before then, Pope Francis has a whole list of other events to see to.
