Our Lady of Guadalupe
Mexico City, Mexico
Our Lady appeared to St. Juan Diego in 1531, leaving her image miraculously imprinted on his tilma. That cloak has been venerated for nearly 500 years and remains incorrupt to this day. The shrine draws some 20 million pilgrims annually, making it the most visited Catholic shrine in the world. The apparitions are canonically approved.
