Arms of Great Yarmouth Borough Council, England

In use since at least 1563; registered 1908

Blazon: Gules three lions passant guardant or dimidiated with azure as many herrings in pale fesswise argent

Motto: Rex et nostra jura (The King and our rights)

The device of the lions dimidiated with herrings is obviously related to the famously peculiar arms of Cinqe Ports, though it is not clear whether this is an intentional homage or another case of dimidiation having an unexpected result.

To [astronomers] would be applied for coat-armor a blue field, and in the same, some of the heavenly bodies, as Planets or Stars, or some of those instruments, wherewith they take their zeniths, elevations, longitudes, etc. also a Serpent biting her tail etc.
