The Iron Crown of Lombardy (Corona Ferrea) is both a reliquary and one of the most ancient royal insignia of Europe. The crown became one of the symbols of the Kingdom of Lombards and later of the medieval Kingdom of Italy. It is kept in the Cathedral of Monza, in the suburbs of Milan.
Thirty-four coronations with the Iron Crown were counted by the historian Bartolomeo Zucchi from the 9th to the 17th century, but the coronations surely documented in history are:
Charlemagne (800)
Conrad II (1024)
Conrad III (1128)
Frederick Barbarossa (1155)
Henry VI (1186, during his marriage with Constance, Queen of Sicily)
Charles IV (1355, at the presence of Francesco Petrarca)
Charles V (1530)
Napoleon I (1805)
Ferdinand I of Austria (1838)
