The WYD Mercy Centre served as the international hub for English-speaking participants during World Youth Day 2016. During that time, we transformed the Tauron Arena Krakow into one of the largest entertainment and sports venues in Poland. During the six days, Mercy Centre hosted over 100,000 young people for concerts by international stars, lectures, and religious services. On the last day, there was a meeting between Pope Francis and 12,000 volunteers.
