The word "Vatican" is derived from the Latin word "Vaticanus," meaning "city on a hill." It is the name given to the area encompassing the Vatican City, a tiny independent state located within Rome in Italy. The Vatican is the home of the Pope, the head of the Catholic Church, and is considered to be the spiritual capital of the Catholic world. It is home to the world's largest and oldest library, the Biblioteca Apostolica Vaticana, which holds more than 80,000 codices and manuscripts, thousands of incunabula, and a sizable collection of maps, coins, and medals. Other prominent landmarks at the Vatican include the Sistine Chapel, the Vatican Museum, and St. Peter’s Basilica. The Vatican also includes the Congregation for the Doctrine of the Faith, the Secretariat of State, and the Papal Curia—the administrative offices of the Catholic Church.
