A notable feature of the pilgrimage sites is the Peace Pole, an 8-foot-tall pole embossed with the words “May Peace Prevail on Earth” in multiple languages—including English, Spanish, Vietnamese, Tagalong, Hebrew, Aramaic, Polish, O’odham (an Indigenous language of central and southern Arizona) and Ukrainian—which is planted in the ground outside each of the designated jubilee pilgrimage sites.

This tradition is part of the Peace Pole Project, which was founded in 1955 in Japan and has spread to almost every country in the world. Before each Jubilee opening Mass, Bishop Dolan blessed the Peace Pole and processed with the congregation into the church.
