AP PHOTOS: A look at the pope's visit to S. Korea
Pope Francis held an outdoor Mass on Saturday for huge crowds in Seoul as part of his five-day trip to South Korea. The Vatican estimated some 800,000 people turned out for the service.
The pontiff's visit coincides with the Asian Catholic youth festival, and on Sunday he will officiate at the closing Mass for the festival at a 15th Century fortress in South Korea.
