Vatican City

Vatican City, officially the Vatican City State, is the Holy See's independent city state, an enclave within Rome, Italy. The Vatican City State, also known as The Vatican, became independent from Italy with the Lateran Treaty (1929). With an area of 49 (121 acres) and a population of about 825, it is the smallest sovereign state in the world by both area and population.
