The Fátima Sanctuary is a group of Catholic churches, chapels and a large prayer square at Cova da Iria, in the parish and city of Fátima, municipality of Ourém. It stands where three shepherd children said they saw the Virgin Mary six times in 1917, and the Catholic Church permitted the cult of Our Lady of Fátima on 13 October 1930.
The sanctuary is one of the main Marian pilgrimage sites of the Catholic Church, with its largest pilgrimages on 12 and 13 May and 12 and 13 October.
