Milan Cathedral, officially the Metropolitan Cathedral of the Nativity of the Blessed Virgin Mary, is an Italian national monument dedicated to Santa Maria Nascente . It is the largest church in Italy (the largest in the Italian Republic, given that the basilica of San Pietro, larger, is in fact in the Vatican City; and third in the world by surface.  We tell you this so you can appreciate more the importance of the gate.  Unused card with a circular “chop” on the reverse suggesting that the postcard came directly from the Duomo itself.  Grade: 1
