In 1985, Pope John Paul II initiated World Youth Day, a worldwide encounter with the Pope for young people that draws millions across continents (3.7 million people attended the most recent WYD in Brazil in 2013). In 2016, the event will be held in Krak w, Poland, birthplace of its founder, newly canonized Saint Pope John Paul II. George Weigel, the preeminent biographer of John Paul II, now presents a spiritual travelogue that further illuminates the life and homeland of one of the most influential Catholic leaders of all time.
