BASILICA OF OUR LADY OF GUADALUPE

Location: Mexico City, Mexico most frequented by: Roman Catholics The story of the Basilica of Our Lady of Guadalupe begins on a frosty December day in 1531, only a decade after the Spanish conquistador Hernán Cortéz toppled the Aztec empire. A 50-year-old Indian peasant named Juan Diego was trudging along between his village and modern-day Mexico City when he encountered the Virgin Mary, who told him to build a church on the site where they were standing. Not one to ignore an order from the mother of Christ,

the peasant relayed the request to the local bishop. A bit suspicious of Diego's claim, the bishop demanded proof of Mary's request. In response, the Virgin (who conveniently appeared to Diego again) supplied the peasant with a bunch of roses in the dead of winter. Needless to say, the bishop was pretty impressed with the bouquet, but even more so by the likeness of Mary that was mysteriously imprinted on Diego's cloak, and a church was promptly built. Today, the site houses the old Basilica as well as a newer one, and millions of Catholics travel the world for a chance to walk inside.

Pilgrims praying to the Virgin Mary there have reported miraculous cures, particularly for alcoholism. (Why alcoholism? We have no idea.) Diego's cloak is also on display at the site, though it's an object of controversy. Scientists argue about the authenticity of his cloak, and historians quibble over the authenticity of Juan Diego himself—some doubting such a man ever existed. The arguments, however, had a hard time competing with former Pope John Paul II's stamp of approval. He visited the Basilica several times, and on a 2002 journey there, he made Juan Diego a saint.
