The Steel Crown of Romania is the coronation crown and principal symbol of the deposed Romanian monarchy. The crown was forged at the Army Arsenal (Arsenalul Armatei) in Bucharest from the steel of a cannon captured by the Romanian Army from the Ottomans during its War of Independence.
Carol I, the first king of Romania, chose steel, and not gold, to symbolize the bravery of the Romanian soldiers. He received it during the ceremonies of his coronation and of the proclamation of Romania as a kingdom in 1881. It is the same Crown used in 1922 at the coronation of King Ferdinand I and Queen Maria as sovereigns of Romania, which took place in Alba-Iulia. The Crown was used also during the coronation and anointing as King of Michael I by the Orthodox Patriarch of Romania, Nicodim Munteanu, in the Patriarchal Cathedral of Bucharest, on the very day of his second accession, 6 September 1940.
