Helperknapp is a commune in central Luxembourg, in the canton of Mersch. It was established on 1 January 2018 from the amalgamation of the communes of Boevange-sur-Attert and Tuntange.
The commune consists of the following villages:
In two referendums held simultaneously in Boevange-sur-Attert and Tuntange on 25 May 2014, the citizens of both communes approved a municipal merger, with 69.51% and 64.09%, respectively, in favour. Based on the poll, legislators of the two communes voted in favor of the merger. Consequently, on January 1, 2018, Boevange-sur-Attert and Tuntange were subsumed into the new municipality of Helperknapp. The name "Helperknapp" derives from the name of a hill of the same name located within the commune.[1]
