The Apostolic Palace is the official residence of the Pope, which is located in Vatican City. It is also known as the Papal Palace, Palace of the Vatican and Vatican Palace. The Vatican itself refers to the building as the Palace of Sixtus V in honor of Pope Sixtus V.
The building contains the Papal Apartments, various offices of the Catholic Church and the Holy See, private and public chapels, Vatican Museums, and the Vatican Library, including the Sistine Chapel, Raphael Rooms, and Borgia Apartment. The modern tourist can see these last and other parts of the palace, but other parts, such as the Sala Regia and Cappella Paolina, are closed to tourists. The Scala Regia can be seen into from one end but not entered.
The Apostolic Palace is run by the Prefecture of the Pontifical Household. The palace is more accurately a series of self-contained buildings within the well-recognized outer structure which is arranged around the Courtyard of Sixtus V (Cortile di Sisto V). It is located northeast of St Peter’s Basilica and adjacent to the Bastion of Nicholas V and Palace of Gregory XIII.
The Apostolic Palace houses both residential and support offices of various functions as well as administrative offices not focused on the life and functions of the Pope himself.
