Depicts a Rose of the Winds.

A compass rose, sometimes called a windrose or Rose of the Winds, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is also the term for the graduated markings found on the traditional magnetic compass.

The use of the fleur-de-lis as north mark was introduced by Pedro Reinel (a Portuguese cartographer, author of one of the oldest signed Portuguese nautical charts), and quickly became customary in compass roses (and is still often used today). Old compass roses also often used a Christian cross at Levante (E), indicating the direction of Jerusalem from the point of view of the Mediterranean sea.

Coat of arms of Portugal divides date. Value divides the engraver's name and abbreviation of the Portuguese Mint and Official Printing Office (INCM).

The coat of arms of Portugal is popularly referred as the Cinco Quinas (Five Quinas) or simply the Quinas (a quina being each of the five escutcheons in form of a cross with five bezants of the Portuguese shield). 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 shield resting in front is composed of seven golden castles, which represent the Moorish castles conquered during the Reconquista.
