A nun prays as workers set up a tapestry featuring Pope John Paul II in St. Peter's square at the Vatican April 25, 2014. Pope Francis will canonize on April 27 the late Pope John Paul II, who reigned from 1978 to 2005, and Pope John XXIII, who was pontiff from 1958 to 1963 and called the Second Vatican Council, a landmark meeting that modernised the Church.
