Today’s town of Neuenhaus was enlarged in 1970 through the amalgamation of the formerly autonomous communities of Grasdorf, Hilten and Veldhausen, the last of which had already existed as early as the 10th century.
Tänast Neuenhausi linna laiendati 1970. aastal endiste autonoomsete kogukondade Grasdorfi, Hilteni ja Veldhauseni liidendamise kaudu, millest viimane oli olemas juba 10. sajandil.
