Lourdes -- Sanctuary of Our Lady of Lourdes, France
Probably the most famous site known for Marian apparitions, starting back in 1858 when Our Lady appeared before a young French girl named Bernadette Soubirous, who is now a canonized saint. The nearby waters are said to have miraculous healing effects on both the mind and body, so it's no wonder that about 6 million pilgrims visit the area each year.
