The municipal area stretches along the district's southern boundary in the Lahn valley and its environs between Marburg and Gießen, and borders in the north on the community of Weimar, in the east on the community of Ebsdorfergrund, in the south on the towns of Staufenberg and Lollar, and in the west on the community of Lohra.
It was formed out of seven former communities in the early 1970s as part of Hesse's municipal reforms at that time. The former communities were:
|Parties and voter coalitions||Share in %||Seats|
|CDU||Christian Democratic Union (Germany)||35.3||8|
|SPD||Social Democratic Party of Germany||30.3||7|
|BfF||Bürger für Fronhausen||34.4||8|
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.
All these partner communities are near Rambouillet.
