St. Peter's Basilica is the largest church in the world, located in the Vatican. Construction began in 1506 and was finally completed in 1626. It can hold 60,000 people, reaches a height of 450 feet, a length of 730 feet, and a width of 500 feet.
St. Peter himself is reputed to be buried under the immense main alter, and many of the subsequent popes are also burried in its catacombs.
It is fronted by St. Peter's square, which is actually an ellipse measuring 642 feet by 485 feet.
In The Templar Concordat, Easter Mass at this church is Ibrahim's dream.
