The Shrine of Our Lady of Fatima is one of the biggest Catholic shrines in the world. In 1937, it is believed the Virgin Mary appeared as an apparition to three shepherd children as they were tending their family's sheep.
From May to October that year, they had the same vision on the 13th day of every month, when a crowd of 70,000 gathered on the site and witnessed a spectacle that became known as the "Miracle of the Sun".
It has been said that the sun spun like a ball in the sky, a phenomenon that led millions to believe in the children's story. The main building is the Basilica of Our Lady of Fatima, with its 65 metre high spire. Outside is the open-air Chapel of Apparitions, built on the site of the visions. This simple, modern structure is open year-round for regular services. It boasts a figure of the Virgin Mary inside holding the bullet extracted from Pope John Paul II after his assassination attempt in 1981.
