The independent Vatican City State is the smallest and one of the most closed countries in the world, which was established in 1929. It is located on the territory of Rome, Italy, and is ruled by the Pope, who is the bishop of Rome. Its size is only 0.44 square kilometers or 110 acres. Moreover, it is 0.6 miles or 1.05 kilometers long and 0.5 miles or 0.85 kilometers wide. However, despite its size, the Vatican contains worldwide famous collections of sculptures, paintings, the library with more than one million books and the same number of manuscripts. Of course, it is worth to mention its notable Gardens, St. Peter’s Cathedral, the dome with the highest viewing point of the Eternal City, the Vatican museums and the Sistine Chapel.
