Depicts a crowned personal standard of the Kings of Portugal with the legend "Luís I by the grace of God".

The Portuguese shield (the Cinco Quinas or Five Quinas, a quina being each of the five escutcheons in form of a cross with five bezants) resting in front is composed of seven golden castles, which represent the Moorish castles conquered during the Reconquista. In the late 14th century, the number of bezants was fixed in five. Late explanations interpret them as the five wounds of Jesus Christ.

The Crown of João VI, also known as the Portuguese Royal Crown is the most recent and only extant crown of the Portuguese Crown Jewels. It was made in 1817 for the acclamation of King João VI. The crown was fashioned in the workshop of D. Antonio Gomes da Silva, the Royal Jeweler. It then became the official crown of the monarchs of Portugal and was used by all the Portuguese monarchs after João VI. Though serving as the monarchy's official symbol, the crown was never actually worn by any Portuguese monarch.
