Nuns take pictures and gesture from a window of the San Joaquin Episcopal Palace in Rio de Janeiro, Brazil, as Pope Francis arrives on July 26, 2013. Pope Francis will meet young convicts here and then return to Copacabana beach Friday where 1.5 million Catholics gathered on Rio de Janeiro's seafront to see him speak the previous night in a massive ceremony for World Youth Day festivities.
