Between May 13 and October 13, 1917, three Portuguese children received apparitions of Our Lady at Cova da Iria, near F√°tima, a city 110 miles north of Lisbon. Mary asked the children to pray the rosary for world peace, for the end of World War I, for sinners, and for the conversion of Russia.
Mary gave the children three secrets. Since Francisco died in 1919 and Jacinta the following year, Lúcia revealed the first secret in 1927, concerning devotion to the Immaculate Heart of Mary. The second secret was a vision of hell.
