The oldest attributed arms of the Principality of Asturias date from the 16th century, and show a quartered shield with the castle of the Kingdom of Castile, the lion of León and a goblet.

The arms consist of a field of azure with the Victory Cross (Spanish: Cruz de la Victoria) of Or adorned by gemstones.

The cross was used, according to the legend or tradition, by the local Visigothic governor Pelagius of Asturias, in the initial battles against the Moors.

The arms must appear de jure in: One stays the existing shields in those declared buildings historical-artistic monuments.
