Electorate of Mainz
The arms were conferred in 1986 and show the castle entrance of the family Echter with their family coat of arms in the inescutcheon. The hazel twig stands for Hessenthal, whose name was once "Haseltal" ("Hazeldale"). The tinctures gules and argent (red and silver) are taken from the arms borne by the Electorate of Mainz.
