Museo del Duomo di Milano

This guide to the Museo del Duomo di Milano opens in 1967, when workers cut open the golden Madonnina crowning Milan's cathedral and found the iron skeleton inside her dying from corrosion. You'll hear about the statue's history since 1774, the blacksmith Varino who built the frame to hold her against alpine wind and lightning, and what restorers found when they finally looked inside. The guide also leads you past gargoyles carved six hundred years ago and stained glass too fragile for daylight, all pulled from the cathedral outside. Look for the case holding the very iron that once stood invisible above the square.
