People wait for the start of Pope Francis' morning mass at the Calixto Garcia square in Holguin, in eastern Cuba, on September 21, 2015. Holguin, a cradle of Catholic faith on the island and also the home region of communist leaders Fidel and Raul Castro, is the only stop on the pope's eight-day, six-city tour of Cuba and the United States that has never received a papal visit.
