The name of the then renamed Diocese of Leiria-Fátima was given by Pope John Paul II on May 13, 1984. The only existing parish in the city has Nossa Senhora dos Prazeres as patron saint. The parish of Serra, as it was originally known, was dismembered from the Collegiate Church of Ourém in 1568.
Due to the Sanctuary of Our Lady of Fátima, located in Cova da Iria, the city has become one of the most important international destinations for religious tourism, receiving around six million people a year.
