Corona de Hierro
Many artifacts have been found, at various locations, which date to European pre-history, and appear to have been associated with ruling and/or priestly elites. For one example, see Golden hat. The oldest European crown jewels of monarchs are: the Iron Crown of Lombardy (9th century, now in Milan), the Imperial Regalia (10th century, now in Vienna), the Hungarian crown (10th–11th century, now in Budapest) and the Bohemian Crown Jewels (1347, now in Prague).
