Francisco de Jesus Marto and Jacinta de Jesus Marto were siblings from Aljustrel, a small hamlet near Fátima, Portugal, who, with their cousin Lúcia dos Santos (1907–2005), reportedly witnessed three apparitions of the Angel of Peace in 1916, and several apparitions of the Blessed Virgin Mary at Cova da Iria in 1917. The title Our Lady of Fátima was given to the Virgin Mary as a result, and the Sanctuary of Fátima became a major centre of world Christian pilgrimage.

Fátima is a city in the municipality of Ourém and district of Santarém in the Central Region of Portugal, with 71.29 km2 of area and 13,212 inhabitants (2021). The homonymous civil parish encompasses several villages and localities of which the city of Fátima is the largest.
