Three Kings Day, or Epiphany (Dreikönigstag in German), is a significant religious event in Köln (Cologne), Germany because the city is home to the Shrine of the Three Kings in its famous Cologne Cathedral (Kölner Dom). This shrine is said to contain the relics of the Three Wise Men (Magi) who visited the infant Jesus, making Cologne one of the most important pilgrimage sites in Europe.
