Vatican City

This smallest country in the world is only 100 acres and it is the headquarters of the Roman Catholic Church and the Pope’s home. While Vatican City has a population of only 1,000 people, there are more than 5 million visitors, every year. The entire country is a world heritage site. It is famous for its iconic architecture and magnificent works of art including Michelangelo’s artwork on the ceiling of the Sistine Chapel and ancient Roman sculptures and Renaissance frescoes. If the Vatican’s artwork was lined up, it would be more than nine miles long or the equivalent of wrapping around its walls four and a half times. The Vatican’s wealth is estimated at 15 billion dollars.
