The treasure of Basilica Sant'Ambrogio in Milan includes high-quality jewelry and rare fragments of the church's original marble dating back almost 2,000 years! The walls and dome in this room are covered with mosaics, and everything has remained almost identical to the time when Milan was the capital of the Empire and a major Christian city. Among the various figures of the Saints, look for the portrait of St. Ambrose: here he seems unusually young with black hair and a short beard, and is depicted quite differently from later versions where he has the appearance of an old man with a bushy white beard!
