The commune of Walferdange is located north of Luxembourg City in the valley of the Alzette. It is part of the canton Luxembourg.

The town of Walferdange lies in the center of the commune, other towns within the commune include Helmsange and Bereldange.

The commune of Walferdange was formed on 1 January 1851, when it was detached from the commune of Steinsel. The law forming Walferdange was passed on 25 November 1850.

Although the commune first came into existence in 1851, there is evidence of prehistoric settlement as well as remains of a very large Roman villa. The Raschpëtzer Qanat, an underground aqueduct near Helmsange was built in the 1st century AD during the Roman occupation. It is said to be the longest qanat north of the Alps.

Walferdange church was built between 1845 and 1852; the main features of its classical facade are two large statues of Père Kolbe and Thérèse de Lisieux, added at a later date. Before official unification of the commune, and even before this church was built, it was religion that pulled the villages of Heisdorf, Helmsange, Bereldange and Walferdange together.

Recognition of Walferdange as an important town came in 1850, when Prince Henry, brother of Grand Duke William III, chose Walferdange as his seat of residence. After the independence of the Grand Duchy of Luxembourg in 1867, the Walferdange Castle was assigned to Grand Duke Adolphe according to the constitution. As an engaged winemaker, he enthusiastically served his guests wine from his own production. The palace was later vacated by the Grand Ducal family.
