The flag of the Region of Murcia was defined in Article 4.1 of the Statute of Autonomy of the Region of Murcia, which established the following: The flag of the Region of Murcia is rectangular and consists of four castles with battlements or, in the upper left corner, arranged in rows of two, and seven royal crowns in the lower right corner, arranged in four rows, with a pattern of one, three, two, and one, respectively; against a crimson or carmine red background The four castles evoke the region's history as a frontier zone caught between the Crown of Aragon and the Kingdom of Castile, and the Nasrid Emirate of Granada and the Mediterranean Sea: four territories of land and sea, Christians and Muslims, adventurers and warriors, all of which created a distinct Murcian culture.
