Our Lady of Luján, Argentina

Every year, 6 million people make pilgrimages to Luján, many of them walking from Buenos Aires. The annual pilgrimage recently was attended by 1.2 million people. The closing Mass was celebrated by Cardinal Bergoglio.
It never ceases to amaze me that the life of the Church is so rich around the world. I had never heard of Our Lady of Luján - a devotion in which millions of people participate every year.
