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 one rear leg, the other lifted against a shield, with the right foreleg raised and the left foreleg holding a shield which bears the City of London's coat of arms, painted in red and white. This stance is the equivalent of the rampant heraldic attitude of the supporters of the City's arms.
