Pope Francis begins a five-day trip to Portugal on Wednesday for World Youth Day, the international Catholic jamboree that is expected to gather around 1 million people.
While in Portugal, Francis will visit the place from where 15th- and 16th-century Portuguese explorers set sail on world-changing voyages to Africa, Asia and South America, a church and monastery that are unique architectural gems, and one of the world’s most popular Catholic shrines where the Virgin Mary is said to have appeared to children.
