The Sanctuary of Fátima welcomed 6.1 million pilgrims in 2025, making it one of the three most-visited Marian shrines in the Catholic world. The site occupies a shallow limestone valley where three shepherd children reported apparitions of the Virgin Mary on the thirteenth day of six consecutive months in 1917, during the final year of the First World War. Construction of the original Basilica of Our Lady of the Rosary began in 1928, its 65-metre central tower visible from the surrounding eucalyptus hills. A second basilica, the modernist Basilica of the Holy Trinity, opened in 2007 with seating for 8,633—the fourth-largest Catholic church by capacity. Most organized excursions from Portugal's capital combine the sanctuary with three additional stops: the UNESCO-listed Monastery of Batalha, the clifftop fishing port of Nazaré, and the medieval walled town of Óbidos. The monastery, 18 kilometres south of Fátima, represents the apogee of Portuguese Gothic architecture, commissioned by King João I in 1386 to commemorate victory over Castile at Aljubarrota. Its Founder's Chapel contains the joint tomb of João and Philippa of Lancaster, carved from a single block of limestone. Nazaré, 35 kilometres west on the Atlantic coast, is known for the Praia do Norte break, where waves routinely exceed 20 metres in winter. Óbidos, 40 kilometres farther south, preserves a complete circuit of fourteenth-century walls and whitewashed houses trimmed in ochre and cobalt. Lisbon to Fátima tour packages tours typically depart between 07:30 and 08:30, with total durations ranging from 10 to 11 hours. Small-group formats cap participation at 8 to 15 passengers, travelling in Mercedes minivans or similar executive transport. Full-day itineraries allocate 90 minutes to two hours at the sanctuary, allowing time to visit both basilicas, the Chapel of the Apparitions, and the colonnade that frames the prayer esplanade. Entry to the sanctuary grounds remains free; donations are voluntary. Guides provide historical narration in English, Spanish, and Portuguese, with some operators offering additional languages on request. The shepherd village of Aljustrel, two kilometres from the main sanctuary, is included in select pilgrimage-focused tours. The stone cottages where Lúcia dos Santos and her cousins Francisco and Jacinta Marto lived are preserved as house museums, maintained by the Sanctuary administration. Visits typically last 30 to 40 minutes. The Valinhos site, where a fourth apparition reportedly occurred in August 1917, lies one kilometre beyond Aljustrel and is accessed by a marked footpath through oak woodland.
