In 2012, I was welcomed in Milan by good friends.

St. Ambrose (a bishop of Milan) is entombed in the eponymous 4th-century basilica, outside of which one can find a column said to display the imprint of the Devil's horns (cf. the Devil's footprint of Munich and the Devil's finger in Poggio Bustone).
As "the only gothic cathedral south of the Alps", Milan Cathedral is certainly an astonishing and unique structure. Its original design is the product of the Parler dynasty of architects (whose other work is in Strasbourg and Prague) and Frenchmen such as Nicolas De Bonaventure, although the sondergotik is more evident than the flamboyant touches. Italian influence is seen in the choice of glorious white Candoglia marble (brought along the navigli), and the occasional lapse into classical details and statuary. Work began on the apse in 1387, while the lantern was not added until 1500, and the majority of the spires date from the 19th century.

Monza shelters in its cathedral the Iron Crown Of Lombardy, one of the oldest crowns in Europe. Napoleon presumed to wear it not long before his demise.
