The Vatican, the Papal See, is the smallest state in the world. Also called the State of the Church, it is a very small enclave within the Municipality of Rome, and therefore of the Italian State. Here is also the seat of the Pope, head of the Catholic Church. But the Vatican represents for everyone and not only for the faithful an essential destination of his trip to Rome. Here you can visit San Pietro, the largest church in the world, rich in works of art, and the Vatican Museums, which host extraordinary collections and artistic works of the greatest painters and sculptors that have ever existed.
