Shield inscribed in an oval with a molded edge, inside a wall with four towers of regular ashlars and doors under semicircular arches, the central one being the highest. In the upper part there is a notch, a geometric figure with two sharp points, a speaking symbol of the name of Huesca and a schematic representation of the Salto del Rodan. At the bottom is the year 1571, the year in which the city's granary began to be built, located next to the Royal Palace, and for which the shield was probably carved; later the building became the headquarters of San Juan, from which it entered the Museum of Huesca. This shield was a symbol of the city since the Middle Ages, the oldest copies of which are found on small wax seals from the 13th century, until the end of the 16th century, and samples of it are found on the front of the cathedral of Huesca (beginning of the 14th century) and in the courtyard of the Huesca Town Hall (second half of the 16th century). Externally it is edged with a gusset with rolled ends.
