Saint Peter’s Basilica is the basilica symbol of Vatican City situated on the namesake monumental square. It’s one of the largest buildings of the world: with a length of 218 metres, it reaches the height of 133.30 metres with the dome.
Construction of the current Basilica started in 1506 and was completed in 1626. It was built on the site of a more ancient basilica erected by Emperor Constantine over the necropolis where, according to tradition, Apostle Peter had been buried after crucifixion.
