The Church of the Most Holy Trinity is a Roman Catholic Church in the Shrine of Our Lady of Fatima in Fátima, Portugal. With a length of 95 meters (312 ft), width 115 meters (377 ft), a maximum height of 20 meters (66 ft) and a seating capacity of about 8500, it is ranked as the fourth largest Christian church in the world. The church was constructed between 2004 and 2007 at a cost of 80 million euros, entirely paid with gifts from the pilgrims.
The first stone was laid on June 6, 2004, was a piece of marble taken from the tomb of Apostle Peter, over which St Peter's Basilica in Rome was built. The stone-laying was only symbolic, as the stone was later installed inside the finished church as an exhibit for the pilgrims.
The Church, dedicated to the Most Holy Trinity, was consecrated on October 12, 2007 on the occasion of the 90th anniversary of the apparitions of Fatima, by the Secretary of State of the Vatican and Legate of Holy Father Benedict XVI, Cardinal Tarcisio Bertone.
