The Holy Father was greeted Aug. 2 by joyous crowds on the 237-acre grounds of the University of Rome Tor Vergata, 10 miles east of Rome, where teenagers and young adults will stay all night in anticipation of the closing Mass of the Jubilee of Youth on Sunday morning.

Young people from more than 146 countries, some wearing colourful bandanas to ward off the hot summer sun, were pressed against fences in the Tor Vergata field as Leo toured the crowd in his white popemobile in late afternoon.
