They show the lion of Jülich, who is taken from the arms of the County, later Duchy of Jülich, as until the 13th century the municipality was part of the Jülich county. The escutcheons in the lower part symbolise the the parish of Warden and their powerful families Collenbach (tilia tree) und von Fürth (pales, lion heads).
