Pope Francis arrived at Monte Real airport in Portugal on Friday where he was greeted by the Portuguese President Marcelo Rebelo de Sousa.
The Pope was due to celebrate a Mass in Fatima on Saturday in honour of two shepherd children, who one hundred years ago, said the Virgin Mary appeared to them.
Tens of thousands of people have gathered in the small town of Fatima to see Francis canonise the two children.
Officials say they expect around 1 million people to converge on the rural town, which hosts one of the world’s most popular Catholic pilgrimage sites. Hotels and apartments were sold out months ago.
One hundred years ago, three Portuguese shepherd children said the Virgin Mary appeared to them in Fatima, and the pontiff is visiting the shrine on the centenary of the “visions.”
