“The weir system of the Schwarzburger Helbe was built in 1282. Helbewehr
The Saxon Helbe was created in 1373.
In its present form, the weir with pillars and weir cheeks was built in 1828/1829.
The concrete parts were probably used around the turn of the century or in 1935 to replace the worn oak planks and piles with which the water was carried until then.
Numerous mills were built in connection with the Helbesystem; they are among the oldest workplaces in Greußen, Westgreußen and Clingen.
With the weir of the Schwarzburger Helbe, the Pfaffenhofmühle (Clingen), Krämermühle (Kiliansmühle, Greußen) and the Grüninger Mühle were created.
There is a 3-4 meter gradient at each of these mills, which indicates that the system is planned.
The stone drive mill (first mentioned in 1476) was subsequently built into the watercourse.
Around 1530, the Kupferhelbe was derived from the Schwarzburger Helbe, which was to operate the Neumühle and the old oil mill (Roesche Mühle Clingen) and the city mill (Greußen).
With the connection of the Saxon Helbe to the weir, the village mill in West Greussia, the Welkersmühle (today Jungsche Kornmühle), the oil mill (today Jödicksche Stellmacherei) and the Lochmühle (today Güntersmühle) were created. "
