The dragon boundary marks are cast iron statues of dragons (sometimes mistaken for griffins) on metal or stone plinths that mark the boundaries of the City of London. The dragons are painted silver, with details of their wings and tongue picked out in red. The dragon stands on its left rear leg, with the right rear leg lifted forward to support a shield, with the right foreleg raised and the left foreleg holding the top of the shield. The shield bears the City of London's coat of arms painted in red and white: the red cross of Saint George on a white background, with a red sword in the first quarter, an attribute of Saint Paul. Saint George and Saint Paul are respectively the patron saints of England and of London. The dragon's stance is the equivalent of the rampant heraldic attitude of the supporters of the City's arms, which may allude to the legend of Saint George and the Dragon.
