Helfenstein Castle

Helfenstein Castle represents the remnants of the fortified castle Helfenstein of the counts of Helfenstein located above the city of Geislingen an der Steige, Baden-Württemberg, Germany.
The castle was constructed, by Eberhard von Helfenstein, at the turn of the 12th century and was frequently enlarged during the period from 1100 to 1380. The site of the castle, over the main Imperial road through the Fils valley, allowed the Helfensteins to observe and control trade in the region. The close connection between the Helfensteins and the Hohenstaufen Emperors during the 12th and 13th Centuries allowed the family to grow and expand. During the peak of their power the Helfenstein family ruled Heidenheim, Blaubeuren, Wiesensteig and Sigmaringen. However, as the Hohenstaufen family lost power so did the Helfensteins. By 1382 the castle was used as collateral for a loan from the city of Ulm. Then in 1396 the castle was totally under the control of the free and imperial city of Ulm.
