These include areas immediately adjacent to state territory, such as the Palazzo San Pio X, Campo Santo Teutonico, and most of the Vatican Audience Hall, among others. A state border runs through the middle of this hall, with the papal throne on the Vatican side and the auditorium already outside the border. Other extraterritorial areas include various palaces in Rome’s Old Town, the papal summer residence Castel Gandolfo, and the Vatican Radio broadcast center at Santa Maria di Galeria.
