The Vatican Christmas Tree, also called the Saint Peter's Square Christmas Tree, is the decorated tree that is erected annually in the Saint Peter's Square directly in front of St. Peter's Basilica in the Vatican City to celebrate the Christmas holiday season.
Almost all of Vatican City's little more than 800 citizens either live inside the Vatican's walls or serve in the Holy See's diplomatic corps in embassies (called "nunciatures"; a papal ambassador is a "nuncio") around the world.
The geography of Vatican City is unique due to the country's position as an urban, landlocked enclave of Rome, Italy.
