Cologne Cathedral – The Shrine of the Magi is the largest, most artistically significant, and, in terms of its content, most ambitious reliquary of the Middle Ages. The relics were brought to Cologne from Milan duomo in 1164. From about 1190 to 1220 a number of artisans worked on the shrine in the workshop of the goldsmith Nicholas of Verdun and in workshops in Cologne and along the river Meuse that continued his work.
