A brief history about Fatima:
On May 13, 1917, Lucia dos Santos, Francisco, and Jacinta Marto were, respectively, ten, nine, and seven years old. As we have said, the three children lived in Aljustrel, a hamlet of the township of Fatima.
After three apparitions of the Angel of Portugal in 1916, the children began to receive visits of a luminous Lady who later identified herself as The Lady of the Rosary. In Catholic language, Our Lady of the Rosary is the Blessed Virgin Mary, Mother of God made man.
The apparitions took place on a small property belonging to Lucia's parents called Cova da Iria, about a mile and a half from Fatima.
The three seers were playing at Cova da Iria on May 13, 1917 when they saw two flashes like lightning, after which they saw the Mother of God above a holm oak. Which is now inside Fatima Sanctuary.
