The Mulleklenkes is a 133-metre transmission tower for the dissemination of radio and TV programmes. It is on the Karlshöhe, a range of hills in the municipal forest of Aachen, near the border triangle and right next to the Belgian border. Mulleklenkes is not a nickname, but the official name of the tower. It is made up of two words from the Aachen dialect: mullen means about the same as 'chatter', and the klenkes is the little finger of the right hand lowered to form a kind of scoop, a distinctive feature of Aachen life with a historical background: it was with the klenkes that workers sorted needles in the Aachen needle industry.
