Coat of armsEdit
The civic coat of arms might be described thus: In gules a bend sinister wavy argent; above, a wing argent; below, seven lozenges argent.
The arms were chosen from many proposals put forth after the greater community was formed. The bend sinister (the band) stands for the river Lahn, which flows through the community. The wing comes from the historic Fronhausen reeves' arms, and the lozenges from the Stewards (Schenken) of Schweinsberg, who were formerly the local nobility; the number of lozenges – seven – also represents the number of constituent communities.
In the community are a connection with the four-lane Federal Highway (Bundesstraße) B 3, and a stop on the Main-Weser railway, with regional and regional express service.
All these partner communities are near Rambouillet.
