„Vert, a deer head Or; between the antler an escutcheon Argent; a crowned, armed and langued azure double tailed lion rampant gules.“ The arms are based on the seal of the town from the 16th century and were granted in 1927. The arms show in the escutcheon the arms of the Counts of Berg. The deer symbolises the large forests in the area.
