Niederwinkel and the estate of Oberwinkel belonged to the Lordship of Wollmerath. Beginning in 1597, the lordship belonged to Lord Zandt von Merl. Odilie von Zandt wed Adam Heinrich von Landenberg in 1698, thereby bringing Winkel into the Landenberg family's ownership. This family bore three silver rings, or annulets, in their arms. This same charge has been taken up in today's municipal arms. The chevron is canting for the municipality's name, Winkel, which in German literally means "angle". Borne in the chief is a pair of tongs, Saint Apollonia’s attribute, thus representing the municipality's and the church's patron saint. Winkel belonged to the Electoral-Trier "Amt" of Daun, which inspired the choice of tinctures, argent and gules (silver and red), which were the ones borne by Trier.
