Frankfurt Cathedral
The Iron Crown of Lombardy (with the title "King of Italy" or "King of the Lombards") was conferred in the Church of St. Ambrose at Milan or at the cathedral of Monza, that of Burgundy at Arles, and the German crown —which came to be the most important of all — was usually given at Aachen, until 1562 when, until the last German coronation in 1792, the Emperors-elect were crowned Kings in Germany in Frankfurt Cathedral, which had already in 1356 also become the established site for the imperial elections.
