Pope Leo XIV took his first popemobile ride through St. Peter’s Square ahead of his installation on Sunday, waving from the back of the open-back truck to the crowd waving flags and cheering “Viva il Papa!

Pope Leo XIV will be inaugurated as pontiff at a Mass in St Peter's Square. The service will mark the official start of his papacy. Leo was chosen as the new leader of the Catholic Church earlier this month following the death of his predecessor, Pope Francis, and a two-day conclave in Vatican City.
