Achalm Castle, Medieval castle ruins on Achalm mountain in Reutlingen, Germany.

The stone ruins of Achalm Castle stand at an elevation of 707 meters, featuring an observation tower built in 1838 on the original foundation.

Constructed between 1030 and 1050 by Count Egino and Count Rudolf, the castle served as a strategic stronghold for the noble Achalm family until the 13th century.

The castle's name derives from Indo-European roots meaning sharp or cliff, reflecting the geographic features of its mountainous location in the Swabian Alb region.

Visitors can access the castle ruins through marked hiking trails from Reutlingen, with the observation tower offering views across Baden-Württemberg's landscape.

The castle stones were repurposed in 1650 to construct houses in surrounding villages after the structure's partial destruction during the Thirty Years' War.
