Lovely as it is, this little country town of less than 8,000 about 75 miles north of Lisbon wouldn’t be on the radar if it weren’t for its most famous citizens: the three shepherd children who, in 1917, saw monthly visions of the Virgin Mary in the Cova da Iria pasture. Today, the site is marked by the Basílica de Fátima, where pilgrims come on the 13th of every month to honor the Virgin and her young visionaries, especially in May and October, when the apparitions originally began and ended.
