In 1917, three young shepherd children experienced an apparition from Our Lady of the Rosary in Fátima, Portugal. During the six visions of the Virgin Mary, she revealed three secrets: one described hell and the other predicted WWII. The authenticity of the third, which the Holy See released in 2000, is still debated. A basilica was built on the site of the Marian apparition in Fátima, Portugal. This is the colonnade around the plaza of the Sanctuary of Our Lady of Fátima.
