St. Peter’s Basilica, one of the holiest sites in Christendom. The current church was built between 1506 and 1626. It is said that St. Peter, apostle of Jesus and the first pope, is buried underneath the main altar. Arnolfo da Cambio’s statue of St. Peter is presently located on the right, before the main altar. Built around 1296, it has become a tradition for Catholic pilgrims who visit the Holy See, to touch or kiss the left foot of St. Peter which has been significantly worn down as a result of centuries of devotion. St. Peters Basilica is the heart of the Vatican and the Holy See.
