Nearly 2 million people will parade through streets Tuesday in one of Europe’s largest Catholic public celebrations, as the Three Kings Procession marks Epiphany across 941 cities and towns nationwide.
The annual event, known as Orszak Trzech Króli (Three Kings Procession), draws participants who dress as biblical characters, wear paper crowns, and sing Christmas carols while following figures representing the Magi to nativity scenes set up in public squares. Last year, an estimated 2 million people participated in the processions across 905 locations in Poland and abroad, according to Vatican News.
