Royal Standard of Spain

It comprises a crimson square, traditional colour of both Castilian and Spanish monarchs, with the coat of arms of the King in the center.

The current flag was adopted when Felipe VI acceded the throne as King of Spain on 19 June 2014.

[2] The heraldic standard, also known as the pendón real, has been, as in other European monarchies, the personal flag of the Spanish monarchs and has been used in events of greater solemnity.

The guidon, of military use, was formed from the reign of Philip II by the same elements of the standard but incorporating the Cross of Burgundy, a fringe and a cordoncillo.

After the dynastic union with Portugal in 1580, the arms of the Monarchy became per fess, in chief per pale, A. quarterly Castile and Leon, B. per pale Aragon and Aragon-Sicily, the whole enté en point Granada and with an escutcheon of Portugal on the honor point; in base quarterly Austria, Burgundy ancient, Burgundy modern and Brabant, with an escutcheon (in the nombril point) per pale Flanders and Tyrol.

It bears the entire coat of arms of the owner, composed precisely as upon a shield but in a square or rectangular shape.

Banners of knights of the Order of the Garter are displayed during their lifetime at St George's Chapel in Windsor.

Juan Carlos I and his successor Felipe VI are concurrently Stranger Knights of the Garter.

[10] The castle of Castile, with three windows and narrow, and the Navarrese chains are carefully detailed in both banners, according to the designs displayed in the amendment to Title II of Royal Decree 527/2014 (for King Felipe VI) and the original contents of Title II of Spanish Royal Decree 1511/1977 (for King Juan Carlos).

The colour of the lion is so darkly in the case of King Juan Carlos[13] and precise in Felipe VI's heraldic flag.
