439 Kodachrome by Walter Meayers Edwards, National Geographic Staff Pilgrims Enter the Papal Domain Through the Keyhole of Bernini's Twin Colonnades Italy by treaty in 1929 recognized the Vatican as a sovereign state, last remnant of the Popes' temporal kingdom, which once included all Rome and much of Italy. Only 1,000 people reside within the walled 108 acres, yet this tiny state commands the religious allegiance of the world's 469,600,000 Roman Catholics. St. Peter's Square sweeps around the obelisk that Caligula plundered from Egypt and set up in the Circus. Pope Pius XII lives in the 1,000-room Papal Palace at left behind the far colonnade. Vatican Library, museums, and Papal Gardens spread beyond (map, p. 444).
