Coat of Arms of the City of Zaragoza

Comes from the top of the entrance of Zaragoza's Leaning Tower (Torre Nueva) in San Felipe Square, the floor of which can be seen. Spanish coat of arms mounted on a choreiform cartouche. There is a lion rampant wearing a crown; we see its full membered body facing right in a threatening pose. Tinctures: gules background and gold lion.
At the top, there is a ducal crown with a gold body set with precious stones and eight rosettes (five can be seen).
At the bottom, there is a chimeric human face. This monster's iconography was surely copied from Renaissance ornamentation developed for the armor of kings and noblemen, such as two burgonet helmets from Milan (around 1550–55 and 1560–65) and two celada helmets owned by Philip III as a child (with a monstrous visor/mask reminiscent of Oceanus) around 1585.
