Fatima welcomes millions of devotees a year who come to pray at the site of a miraculous apparition of the Virgin Mary here in 1917. Three shepherd children had a vision of Mary, who reportedly reappeared on the 13th of each of six subsequent months calling for peace in the world. On the day of the final apparition a crowd of over 70,000 people had gathered and claimed to witness the Miracle of the Sun, when illnesses and disabilities were cured amongst the onlookers and the sun appeared to shake and tremble in the sky.
