Hübichenstein, Natural monument in Bad Grund, Germany.

Hübichenstein is a limestone cliff formation near Bad Grund that rises approximately 50 meters above the surrounding land. The two connected rock peaks are composed of Devonian reef carbonate and dominate the local landscape.

In 1897, a large bronze eagle monument with a three-meter wingspan was erected on the summit. This installation marked an important moment in the local history of commemoration and landmark identity.

Legend names the dwarf king Hübich as ruler of the rock; he gave silver pine cones to the poor and forbade entry to his realm. Soldiers shot at the summit during the Thirty Years' War, after which Hübich was never seen again. He is still considered Bad Grund's unofficial patron.

The rock is reached on forest paths and trails from parking areas on the B 242, about 1.1 km north of Bad Grund's centre. A steep stone and rock stairway leads onto the lower of the two crags, where a viewing platform gives a wide outlook and a rear view of the bronze eagle.

The two connected rock needles are remnants of Devonian coral reefs, made largely of reef carbonate rock from the Givetian stage of the Middle Devonian. Like the nearby Iberg, the limestone contains nest-shaped feldspar and limonite deposits, and small caves and pits lie beneath the rock.
