Cova da Iria ("Irene's Cove") was a land belonging to Lúcia Santos' family in Fatima, Portugal. Lucia was one the three visionary children who, according to Roman Catholic Church, received several visitations and messages by the Blessed Virgin Mary, Mother of God. The Children used to frequently pasture their sheep on this land, and it was on May 13, 1917, around noon, that Our Lady of Fatima appeared to the three of them. The story goes that suddenly there was lightning, and the children, Lúcia Santos and Jacinta and Francisco Marto, thinking that it was going to rain, began to run. Then, just above a oak tree, they saw a beautiful lady made of light, holding a rosary in her hand. Our Lady of Fatima spoke to the children and told them not to be afraid. "I come from Heaven", she said.
At Cova da Iria, on a huge esplanade, a little chapel was built, in the place the apparitions took place. Since The Roman Catholic Holy See, has officially approved the Fatima apparitions and the messages given to the three shepherd children, the place has become an important center of pilgrimage where peoples from all over the world go on a spirit of faith and penance. The Chapel has been expanded and is now much bigger.
