mainstream catholicism as a whole is represented by the holy see (, "holy chair") of the vatican city state (italian: ), a walled enclave within rome, italy. inside the vatican the largest church in history, st. peter's basilica (l.: "basilica sancti petri"), is the location of the papal office and the living quarters of the pope (in the apostolic palace), as well as vatican hill – atop which are saint peter's tomb and place of crucifixion, his throne, and his baldachin. outside st. peter's square are many more churches throughout the vatican and outlying rome. one important landmark is the sistine chapel (l.: "sacellum sixtinum"; i.: "cappella sistina"), in which the papal conclave takes place.
