An important Marian pilgrimage took place along 1,242 miles of French roads last summer, tracing a giant "M for Mary," from June 1st to September 13, 2020, stopping at five major French sites of Marian apparitions. Pilgrims walked behind a statue of Our Lady of France, carried in two horse-drawn carriages that followed different routes:
The next day, the procession went to the business district of Paris called La Defense, where Mary's carriage circled around the large square to bless the first business district in Europe. The hundred or so faithful present for the occasion prayed fervently for the nearly 180,000 people who work in the skyscrapers above. Afterwards, they attended Mass, right next to the Grande Arche of La Defense.
