The Shrine of the Three Kings (German Dreikönigsschrein) is a reliquary said to contain the bones of the Biblical Magi, also known as the Three Kings or the Three Wise Men. The shrine is a large gilded and decorated triple sarcophagus placed above and behind the high altar of Cologne Cathedral. It is considered the high point of Mosan art and the largest reliquary in the western world.
Legend recounts that the "relics of the Magi" were originally situated at Constantinople, but brought to Milan in an oxcart by Eustorgius I, the city's bishop, to whom they were entrusted by the Emperor Constantine in 314. The relics of the Magi were taken from Milan by Holy Roman Emperor Fredrick Barbarossa and given to the Archbishop of Cologne, Rainald of Dassel, eight centuries later, in 1164. The Three Kings have since attracted a constant stream of pilgrims to Cologne.
"In the days of Philipp of Heinsberg the shrine of the three magi was built. This was told to me by some eyewitnesses who were present when the three magi were put into the shrine." — Vita Eustorgii
Parts of the shrine were designed by the famous medieval goldsmith Nicholas of Verdun, who began work on it in 1180 or 1181. It has elaborate gold sculptures of the prophets and apostles, and scenes from the life of Christ. The shrine was completed circa 1225.
