The primary visionary was Antonie Rädler, who, while sick during the 1918 flu pandemic, reported a healing apparition of the Blessed Virgin Mary.

[1] On December 15, 1936, Rädler had another apparition of angelic choirs singing: "O Mary Immaculate, conceived without sin, beloved Lady of Victory, pray for us".

I shall crush the head of the infernal serpent with my feet ... People will come to this place in large numbers, and I will pour a flowing of graces over them.

[2] Today, approximately 500,000 pilgrims visit the shrine each year, and spiritual conferences are held weekly at a pilgrimage center.

The new structure was opened in the Fall of 2000, with a formal blessing by Darío Cardinal Castrillón Hoyos, president of the Pontifical Commission Ecclesia Dei in December 2000.
