May 13th marks the 102nd anniversary of the first of 6 apparitions of The Virgin Mary, in Fatima, Portugal. The apparition is said to have visited 3 young shepherd children as they worked in a field, telling them several prophesies. 2 of these secrets were later revealed to have come true, the 3rd is still very much a mystery. The apparition would continue to visit the children every month until October 13th, when she is said to have performed a solar miracle to over 100,000 people who had flocked to see. Rob Davies visited Fatima to find out more about the story. Why did the Vatican hide the prophesies for so long? Does the 3rd prophecy really predict the end of the world, as many people fear it might? Did 100,000 people really witness a miracle? This place really is the center of one of the 20th Century's greatest mysteries.
