Saint Peter's Basilica is one of the most impressive basilicas in the world and stands at the heart of the micro country of Vatican City. The papal enclave is an independent country that is inside Rome (it is also the world's only theocracy).

St. Peter's Basilica is a stunning work of art and one of the largest churches in the world (in fact it is the largest Cathedral in the world by internal area).While visiting the Vatican City, many people only visit St. Peters and the Sistine Chapel, but there are many other rooms in the Vatican that tourists are not normally allowed to see.
