'Gemenge Plaz' means the town hall square.
Walferdange's town hall has its address on the Place de la Mairie. The commune itself is younger than its villages: Walferdange, Bereldange and Helmsange, which took shape in Frankish times and the early Middle Ages, belonged politically to the 'landmairie' and then to the municipality of Steinsel. They became an autonomous parish in 1843 and an autonomous commune in 1850.
