This is a major pilgrimage centre following the Virgin Mary's repeated apparitions to 3 young village children in 1917. Over the years Fatima celebrity has increased exponentially. With two major annual pilgrimages a year attracting hundreds of thousands of people, the place has expanded with bigger and bigger places of worship. A small plain chapel on the site where the apparitions occurred is under the cover of a larger building, and then The Chapel of the Apparitions is a large building behind this and contains the tombs of the children and then there is the huge Holy Trinity Basilica on the other side. This dramatic contemporary space can hold up to 9000 pilgrims. Between these three is a paved esplanade that can hold 1 million people and a few statues of various Popes who have visited over the years.
