[2] The first official description of the coat of arms remits to the elements of the flag and is composed as follows: «Article 4: 1st.

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 coat of arms will have the same symbols and distribution as the flag, with the royal crown.»Given the lack of precision to define a correct blazon, was approved a decree on 8 June 1983 blazoned the shield of the region as follows: «Article 1: According to Article 4.2 of the Statute of Autonomy, the Region of Murcia has its own coat of arms.

At the top of the escutcheon, a royal crown, for being Murcia a former kingdom.»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 Kingdom 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.
