Pope Benedict XVI has been celebrating an open-air Mass at the Catholic shrine of Fatima in Portugal. Church officials said as many as half a million people turned up.
The Mass comes during a four-day visit to Portugal by the Pope, timed to coincide with a reported apparition of the Virgin Mary in Fatima 93 years ago.
The visit also comes in the context of a Catholic sex abuse scandal, which the Pope blamed on "sin within" the Church as he travelled to Portugal.
During the service, priests lined up under the shade of white umbrellas as they administered communion to the faithful.
While one boy found a spot in the sun to catch some rest.
Fatima is one of the most popular Christian shrines in Europe. Many people travel the last few hundred metres on their knees as a sign of devotion to the Virgin.
Pope John Paul II helped popularise Fatima, visiting three times. Pope John Paul beleived Our Lady of Fatima helped save him from an assassination attempt on another anniversary of the reported apparition - 13 May 1981.
John Paul placed the bullet that nearly killed him the the statue's crown, and his successor prayed in front of it on Wednesday.
Pope Benedict also prayed at the tomb of the three young shepherds from Fatima who claim to have seen the Virgin in 1917.
The night before, the Pope had attended a candle-lit vigil at the Fatima shrine.
