Pope John XXIII takes a walk on the terrace of a IX-century tower in the Vatican gardens April 15, 1963. The Pontiff found the tower - once a fortress and later the Vatican observatory - abandoned and in decay. He liked it, particularly for the beautiful view from its covered terrace, embracing a great part of Rome and the surrounding country, in clear weather as far as the sea, distant about 25 kilometers (16 miles). He had it repaired and spends many days working in the studio he has had arranged there. (Ap Photo/Luigi Felici)
