Saint Eustorgio, the first bishop of the city, brought their relics from the Holy Land to Milano, and ordered a church to be built to be the site of their tomb.
Such church is the Basilica of Sant'Eustorgio.
In the XII century Milano was overthrown by the Holy Roman Emperor, Frederick Barbarossa, who sacked the city and brought the relics of the Magi to Cologne, in Germany, where they have been housed until the XX century.
Only in 1903, after long negotiations, fragments of the bones and garments (two brooches, one tibia, and one vertebra) were sent back to Milano, and are now kept in a bronze urn above the altar in the Chapel of the Magi, in Sant'Eustorgio.
Milano's place in the legend of the Magi is reaffirmed by the procession of the Magi, which takes place every 6th of January from the Duomo to the Basilica.
And a lasting homage to the memory of the Three Kings is the eight-pointed star, rather than the traditional cross, that surmounts the Basilica's bell tower.
