Senyera

The Senyera is a vexillological symbol often called "the four bars", much older than the Crown of Aragon.

The Senyera pattern is currently in the flag of four Spanish autonomous communities (Aragon, Catalonia, the Balearic Islands, and the Valencian Community), and is the flag of the historically Catalan-speaking city of Alghero (Catalan: ''L'Alguer'') in Sardinia, Italy. It is also used on the coat of arms of Spain, the coat of arms of the Pyrénées-Orientales department and of Provence-Alpes-Côte d'Azur, the flag of Roussillon, Capcir, Vallespir, and Provence in France, on the coat of arms of Andorra, and on the local flags of many municipalities belonging to these territories. The Senyera (sometimes together with the flag of Andorra) is also used informally in Catalonia to represent the Catalan language.
