I spent my second day in Rome visiting the Vatican. To get to Vatican City, I took Metro A from Termini to Ottaviano - St Peter's Basilica station. Ottaviano is a short walk from St Peter's Basilica.
Vatican City, known as the smallest country in the world, is encircled by a 2-mile border with Italy (Rome). The head of Vatican City is the Roman Catholic Pope, known as the Bishop of Rome.
I arrived at Vatican City early in the morning and was one of the first to enter St Peter's Basilica.
