The Government of Catalonia states about its official symbols that it may derive from 11th century or 12th century pre-heraldic symbols and the County of Barcelona's coat of arms, in which the yellow and red bars were vertical, while horizontal in the flag. The dynastic coat of arms became also the one for the lands ruled by the counts. It is thus present in the flags and shields of the territories that once were part of the Crown of Aragon and also in the arms of Andorra, Provence-Côte d'Azur and Sicily among others.
